Description: This passage is mainly about student desmos. In this passage, the writer tells us how to do a desmos art project and how to get a basic one if we don’t have any idea about that.
This is the second article for the desmos art project, so we’ll call it part two here, so it is what I want to show to help you get an idea, if you’re totally without ideas about what to do, you want a real basic one, let me show you what you can do, let’s show you on desmos.
So this is the thing, this is what we create with our paper folding activity with the the pati paper, you can create this with not too much effort on desmos if you know what you’re doing, and you will know what you’re doing, because I’m going to help you out, so these are all straight lines, now a straight line can be written in slope-intercept form.
So if we draw this on graph paper, we should yield once we find one equation, and we should be able to figure out a pattern and find the rest of them, and copy and paste, and change the slopes and the y-intercepts and adjust them, so it makes this pattern.
So each one of these is the individual line, there are about 15 lines, but it doesn’t take too much time on what you’re doing, and once you get handy with copy and paste, so let’s jump into it, let’s take a look here, if you have a graph paper, set up, the way that you’re going to do this on graph paper is that I do that one 15, but we’ll do this one with 20, I remember from 20 to 20.
I’m going to connect the 20 up here with 20 at the top, put the one on the bottom, there you go from 20 to 1, now this thing will stop autofocusing, maybe it’ll stay like that, so that’s one line and that has a negative slope, and as you do the rise in the run, you can figure that out, it goes down 20 and across one, so your slope will be negative 20.
You can tell what the y-intercept is, because it crosses there, so the next line will go from 19 to 2, so think about where you’re going down, how far you’re going down and how far you’re going across, which will say your slope for that one, it doesn’t look too good yet, but if we connect 18 with at 17 with four and sixteen with five, this slowly starts to curve, it doesn’t look like it yet.
But that’s the basics 21 to one, so you can find the slope down 20 across 119 to 2, you can find the slope 617 1 and so on, it’s all, so on slope and y-intercept and all you need is y equals MX plus B, your slope and your y-intercept, it’s what you will do in desmos, you add in a whole bunch of different equations, so let’s go back to desmos.
What I will do is to throw a new blank graph, and we’ve graphed our first one, let’s zoom this over here, so we have zoomed out to xx, there we go a little more and drag it over here, there we get about right, so I’m going to go down to 22 about 1, so we said y equals negative 20x plus, I leave the Y out, so there’s your line there.
Now it’s the next one that you’d put throw on the next quiz, and then the next one and the next one and the next one, I’ll leave that for you to do that, one other thing that I’ll tell you is that you don’t want this line probably to go forever, so since it only needs to go from there to there, for this one I only need to go from 0 to 20 on the y axis, in that way it only shows me from that part, it’s the same thing.
The next one will only going to need to go up to 19, the one after that will only need to go up to 18, because it will stop at 18, so think about this, and I think about that’s all what you will have to do, then copy and paste this, that’s the same line, but you now shift the change that slope, and change that y-intercept to get your next line.
If you’re wondering what the slope y-intercept is, go back to your graph, figure out how far you go down, how far you want to cross, that’s your slope for the second line and third line, how far you go down, how far across the fourth line, because slope is simply rising over run, and keep in mind that if you’re going this way, all your rise will be down, you’re going down for all of them.
So try it out, play around with it, and once you get the hang of it, I’m sure if you get the hang of it, you can make something spectacular, something far beyond this one, I look forward to seeing what you create, and we’ll play her out with the computer, have a great weekend everyone.
