Hi, Charlie. Hello, are you well? Yes, I will. Good, good. Do you want to try this to start? Okay. Three sums means equal or. Yeah what is some some is adding up. Sorry just one moment. Hold on sums are adding up. So so this one is I need to drasome number I need to put some number in in in here and make these three equal right? Make not equal to each other but make them all correct. Make four use all twelve numbers Yeah. Okay. Oh, sorry. You. Can move those. Okay. Have you got any thoughts? Yes, I can't find any glue or or some. I would look, I. Would look at the last the last digits. Yes. Because they end up it will be a last digtoo. Yeah, If wechange the font to. Like so. We know these three can't go together, can they? It will be eight. We know these three can't go together. Yeah it will be five. We know these three can't go together. That would be seven. So. If we got okay, let's take say we got one, 27 went together. That would be zero. That would be okay. And. We would have to do 676, and if two, it will be five. Okay six, 72 would be five. And so so then thatbe, what would are seven? Okay, so that's not right. Okay? So if we had one, two, seven and zero, then we would definitely need six there and we would have one, seven, zero, two. That's. Okay, so then webe left with nine. 59 zero one. So that's not right, is it? Yeah. Oh, no, wait, if you put nine there. Then you would get 111. But. You can't get, Yeah and then 59Yeah one and then five Yeah. Gives you zero. Okay. So would be there would but there would be a two here, wouldn't there? There would be a two here. Yeah. They are two old 22 zero. Now what I mean is, if you're doing six plus six plus nine, it's 21. So you would have a one there and you would have to have a two. Added on. Same here. Six plus five is eleven, plus nine is 20. So you would also have a two here to Carry, to Carry over. There two zero. Yeah but what I'm saying is you would Carry the one over. When we talk about adding up this, the single digits, you mustn't forget that you've got a one to Carry over, you've got a two to Carry over and you've got a two to Carry over. Yeah. Yeah the digit is right. The single Yeah. Okay. So what I mean is you've got ten to Carry over, you've got 20 to Carry over and 20 to Carry over. Yeah, I know. But Yeah I mean here are two zero in the last bati find. Yeah, okay. All right. So so that's all okay, isn't it? All right, so. But there is a problem there. Why is there a problem? There's a big problem. Only why 100? It's too small. Yeah. It's the smallest, right? Yeah but look, can we. Can we just swap it out, by which I mean, put it on top. Yeah you can put zero up and put five down. Nice. Nice, that will be right. Lovely, perfect. Okay. So we got five at the bottom. So some of these numbers, there's only one of them. So that's 305, isn't it? That's got that would if that's five it's got to be 305, isn't it? Yeah. But that's also a problem, isn't it? Yeah and also very small. It's too small. Yeah, it's also very small. So actually the none of the answers. So okay, let's think about a different strategy. This is not an answer, is it? No question. That as in this, these cannot be at the bottom. That can't be at the bottom. That can't be at the bottom. That's too small to be. I think all of these are too small. Yeah. So it looks like, well, actually the biggest numbers have, the three biggest numbers have got to be at the bottom, haven't they? Yeah. So Yeah, when I first do it, I just put these these three in the in the bottom. But I. What I don't know why can't find the correct answer. Okay, let's try the three biggest numbers at the bottom. It might not be the three absolute biggest, I suppose. It might not be all three because I suppose it depends what we're adding. It's hard, isn't it? Can I leave it with you on the board? Okay. Yeah. And you can just play around with it and we'll do something else for now because we're going to take a deep dive. It's it's a tricky puzzle, isn't it? So but it's it's good because can you so basically, we want to do we want to do number one first. Okay. So graph one is y equals two x plus one, okay? And if you want to, you can fill them in here to help you. And then we want them on here as coordinates. Do you think you understand what to do? So I need to write down, I need to find, where is why? Wherwhat right for each of those x values. Yeah okay. But what about under this one? So we are looking, we're starting we're starting with number one. We want the graph. We want the graph of y equals two x plus one. This is the graph we're trying to make. So if zero, if x is zero. Right? This is going to be the number for y. If x equals zero. Why one Yeah is two times zero. Plus one. Yeah Yeah, so one would go there. So. And on the graand on the grass here wait and here we only need to write in this right? Not not this no that's that's the late that's other ones Yeah so here would be on the graph would be here Yeah, okay, I know you know how to do it Yeah. So no might find I need to find this number in this big picture. Yeah and they might not all fit, right? They might not all fit. There's no minus seven. No. So if it doesn't fit, just leave it off. Okay. You know, it's the. It's too small. It's just the biggest degree. Okay. Wow. All right. Yeah, there we go. Okay, let's put a red line on. Okay? It's a bit, it's a bit off. Let's try. Yeah, okay, nice. Alright, so then you can try the next one. Number two. Oh no, sorry, leave it on though. Leave it on. I want to compare them right? So we want to compare them. Okay, so Yeah. Okay, so the blue one. Is the first one right? You can start the second one. Y equal two x minus two. Okay. So that's the red line. Yeah. Okay. Next. Does the function of minus four equal minus two? No, it's Yeah minus two Yeah Yeah Yeah Yeah Yeah, it does. Yeah, Yeah. And then add two. Wait. Minus three. Divided by two. Equal -1.5 and then plus two plus two plus two equal 0.5. 0.5. Shall I write under it because it's too Yeah small spaces or you can just graph you can just graph them straight away if you want if you just want so what was it minus three 0.5 so be there right? You can just put it there straight away if you want. Maybe I should write it first minus two. Yeah. Minone one to put two 0.5, 2.5. And two divided by two equal one. There's three. And. Three divided by two equal 1.53 point 53.5 and then four Yeah. Finish, I need to write on it. Zero y is zero y is zero and x is minus four. So it's here. Yeah. Now. The y is 0.5, y is 0.5 and X, Y is 0.5 and x is minus three is here. Minus one. One and minus two, y is one and minus two. So it's here and then 1.5, x is 1.5 and it will be here minus one, right? Yes. So now, I think last next one is here. Yeah x is zero and y is two, right? It will be like there. Aha. Grab Pitdown. And the air. Hair and hair. So now we can have a wine. It's here to here. Okay. Nice, right? Okay. All right. So the orange line is y equals half x plus two. Yeah. Okay, next. So next one. X plus y equal two equal two, so y is 67. No not seven. Oh no. Oh I'm so annoyed. Oh sorry, I don't hold on right just bear with. I can get a bit back. Have to. I can hear very carefully. Okay, okay, let me just get it back for you. Okay, sorry about that, Charlie. Right? So. Right? You Carry on. Okay, there we go. Sorry about that, right, Carry on. All right, what one do you have there? Maybe I should. Okay. I think I need put this one here and then. Six hair, eyes and. This one here or air. Maybe I should write it again. Too. Minus. And then six no and minus three x is minus three y is five. Y is five, no five. So no four and there's a 33 we could have and minus one. Circle. One minus one. Okay. Y Y is two, y is two and x is zero. So here's another and y is one and x is one. Y is one and x is one. There is another and y is zero. X is two. Hmm. Maybe I got the wrong way, I think. No, you haven't. Let me see. Okay. No, you haven't got the wrong way. Y is three and x is minus one. So here is one and Y, Y is two. Y is two. So here it is right. Y is two and x. Yes, I got wrong. Why is two and no, no, no, X, Y is two and x is zero. Here it is. Y is two, y is two, and x is zero and 11, it will be like. This so it's going the other way. Yep, so. 20 to line and. Okay. Okay. So let's just try let you Carry on. I'm just going to try and get the line a bit more. Right? The bottom is not very good. Maybe. I should put it again. Aha. And this one goes. This. It will be like these. I think. Yeah, that's better. Okay, so the Green line is y plus x plus y equals two. Okay, one more. To go. There's another one y equal x minus two y equthree x minus two y. Equals three. So x this 12y it should be one. So. The first one x minus two y equals three, so minus two minus minus four minus. Minus four minus. Minus four minus minus. Three. Sometimes it can be easier to just even though you're I know it, you're reading from left to right, you're reading this way. Sometimes it can be better to just start with one and zero. Oh Yeah, Yeah, Yeah, Yeah. And then because. Once you've got those. Yeah, it's not very easy. X minus two Y X is zero equals three, so x minus two y. Zero zero minus what equals three zero minus minus three so minus three equal to y Yeah so y equal. It's 1.5. -1.5Yeah Yeah, -1.5. -1.5. Here. One minus minus one minus two, one equals three, so one needs to minus minus two equals three, so two y equals minus two, y equal minus two, so y equal minus one. Nice. Two x xis two so two y equal, so this one is 0.5. I know how to do it. 0.5. And -0.5 why? -0.5-0.5, -0.5 and this is zero and this is. One. No, no, this is my 0.5. Nice. Yeah, nice. Maybe I can write. It. X equals zero and x equals x equals zero and y equals -1.5. Y is 1.5 is here x zero? So here is the first one. Maybe I'll change the color, right? So. 1.5 here. Yeah this is 11x equals one and x equals one and y equal minus one. So here is another and. Two equals -0.5. Don't know, x equals two, x equals two, okay, y equals -0.5. Aa, Yeah Yeah Yeah. X equals two and. Minus. Zero, I write wrong in the first one. X is zero and y is -1.5. Yeah first one is that here? Next, next and next and next. So I can write a. Line. So go on, go on, go on. Nice. Okay. And then we can also see Charlie, that here we've got a pattern zero, you know 0.5, zero, -0.5, minus one, -1.5. So the next one should be minus two. Does that make sense? -2.5. Yeah. Minus o three. So you can see that that matches with the graph. Yeah. Yeah. So what we see on the graph with the numbers is the same. As what we see. With the line. Yeah. Yeah Yeah as it Yeah as in the one I wrote I wrote say minus three minus three us minwe can see minus three minus three here. Yeah here and it's on the line. Yeah, Yeah, Yeah. Okay, great work. We can check. Yeah, we can check. So great. Look, you did some really good work there. We've got five graphs. So it's a real it's a real kind of big item of work there. So Y X sorry, x minus two, y equals three. Okay, so let me cut these out and I'm going to put them onto your board so we can keep what you've done. Okay. Because I would like you to notice Charlie, what what do you notice about the graphs? Like do you see can you like can you see. For example. This one says two x plus one. The blue one. And do you notice that. You mean this one? Yeah, this one says x plus y equals two. Do you see this too here? Yeah. So I see too. Yeah okay, so x two x minus two. Do you notice it there? What do you want to say? Well, the orange line also says half x plus two, and here is two. So the number, the number is actually saying where the graph touches the y axis. Here it's here. It's written differently, so that's why it's different. Okay, what can I ask you? What do you notice about these two lines? This one? And this one. How to say it it means here it's everywhere. Here it will be same same long. They're parallel. Yeah because they are like like rectangle. Yeah so they are parallel lines. That's to do with this. Two x and two x. Yes. Yeah. Okay. Look, great work. We're at the end of the session, so we're going to continue with that next time. Okay. Into recognizing the graphs. Yeah you still there? Oh Yeah. Recognizing the graphs and recognizing the gradient and working more with the algebra. Have a great week. See you next time. Bye. Thank you.
