Okay, so here we have this chart with the price, um, off a monitor and the quantity demanded. Demanded, depending on the price. So part am, this problem is asking us to pluck this points, um, into a plane. Okay, so we're gonna pluck this things, So we're gonna have the y axis, which is going to be, um, the quantity demanded. This is the quantity. This is the price. Um, we're gonna have a go up by twenties, and then our prices. We're gonna have it go up by fifties. Okay, We're gonna make this girl farther, okay? Now we're going to graph this. That we have 100. I'm 50 and 100 Bennett right there. 280 150 16. 340. Okay, so those would be just plotting the point. OK, now, Forbidden asked us to prove that this is a linear function. So what we want to do here is see if we have a, um, the same slope. Okay, So we're gonna look at our numbers up here, and we're gonna find the rate of change between the different points. Okay, So this one, we would have a t minus 100 over 200 miners, one of 50 which would then give us a negative 20/50. Okay. And would do the same thing with the other one. We have 60 minus 80 all over 2 50 minus 200 because gives us also in negative 20/50. So if we notice we have the same rate of change, so right, greater change. ISS a native, 20/50 we're going to write. This is a decimal, which is a negative syrup point for okay, and because they have the same, um, rate of change, Um, this ISS a linear function, and we know that it's a function because every exercise, its own Why, Okay, Now, let's write, um, a linear function to represent those points. So what we want to do is we have this lope or slope is this, But we need to know if we have a y intercept. So we're gonna want to find that y intercept. We're gonna choose a point. We're gonna, um, choose the point. Um 151 100 and we're gonna plug it into our like equation, which would look like what equals and Mexico's be right. And so Or why? Then it's 100 or the slope is, um, if you're negative 0.4 x and our X, actually iss 1 15 and with isil for B. Okay, so, um, negative 0.4 times 1 50 is a negative 60 and then we're gonna add 60. And so we have that, um, b is 160. So then our equation iss we're gonna write it asked que off p this equal to a negative syrup point for P plus 1 60 Okay, so that is our equation. And now, Part D is asking us to see, um what is going to be the implied domain off dysfunction? So domain is we're looking at the excess, right? So let's go up to a graph. We're looking our access, and so we want to know, um, where does it start? Where does it start? And where is it gonna end? Okay, so Well, we know that it's gonna, um it started zero. But how far is it going to go? So we need to see where do we have our other intercepts? And where is X? Um, where is why actually where's wise steer during a plug in a syrup for why? And so we have You always offer X. So we're going to move that 1 60 over to the other side. We're divided by a negative 0.4, and we get 400 here. So this counts Is that whenever we have, Um, but price is 400. We have Sierra demand. And so that tells us that then our domain goes from zero. So if we're prices zero, we're gonna have a 160 demand. Um, and it goes all the way to 400 because after that, we don't have any the man. Okay, well, part is asking us to graft dysfunction. So what we're going to do is just We know they have a point here, and we have a point there. So we are just going to connect. Um, kind of those points over line is gonna go through the points. Okay, in that kind of didn't work, but supposed to be a straight line. Okay. And then part f asked us to, um interpret. Oops. Sorry. Let's see. We're going to be interpreting the slope. So our slope is our negative 0.4. So what does that tell us? So our slope, remember is our rice over run. Okay, So since this is a negative, this will tell us that it the price increases by $1. Then the quantity demanded We'll go down because they will go. Will decrease by syrah 0.4 of a monitor. Okay, Now Part G then asked us to interpret the intercept. So what are our intercepts? We have zero in 1 60 and we have 400 0 So zero is their price. If your price is just X zero Sorry. If price this year then we have a demand of 116 mothers. And then the other one is If our price is 400 then we have no demand. You said those are gonna be your answers.
