Hi, welcome to this question right here. We have a question here, trying to find a slope-point form. So this is a slope-point form. For all these lines equations over here. So let's go ahead and quickly find all of them really. It's pretty straightforward. The A line over here, okay? Now, all you have to do is figure out the slope and pick one point of your choice. So, for example, if I'm going to do the A over here, I'm going to pick, for example, this point right here. Okay? The x intercept. It's really up to you to pick any points you like. So, the x intercept right here is going to be negative 5, 6, 7, 8, negative 8 and 0, right? So keep the first y as a variable, don't change that. And then you're gonna subtract the y value of this point which is 0. So you'd be subtracting the 0 equals to the m, which is the slope. Now, the slope should be easy to calculate, because you're doing a rise over run, right? So, you go up 1, 2, 3, 4, 5, 6, over 2. So 6 over 2 means 3. So, we're going to have a slope of a 3 and with an x minus a negative 8, okay? So, there's technically, it's just going to be a positive 8. So to do a little bit of simplification right here, usually that's what they're looking for, but if you're subtracting 0, just remove that. So, it would just be y equals to 3 and then x plus 8 is your final answer for this one, okay? Now, coming to the B, what we have is the same thing. You pick a point and you find your slope and you're plugging the numbers in. So, again the first y and the first x stays as a variable. So, y minus my first point, so my point here, I'm going to pick--You know what? You can actually pick this point if you like, okay? You can pick other points if you want, so why not pick this one right here, okay? So, this one right here is a 7 and a 1, right? So, here's my 1 right here, and my slope, I'm going to add this to the slope later, before I forget my x. It will be x minus 7, so I'm going to put x minus 7 right here and I'm going to put my little slope over here, which is going to be up 1, left 2. So, it will be up 1, but a left 2, so it's a negative number. So, that is your slope point-form for this equation right here. Now, what's my next one, which is C. Now, for C and D I would not recommend that you even actually do the slope-point form right away because you know it's missing a lot of stuff. So, if you know you're looking at C and you're looking at D, right? So, let's do C first. So, if I'm looking at C right now, it's just a vertical line going straight up. So, it's going across the x when the x equals negative 2. So , it's just x equals negative 2 and that's it, okay? Because everything else has kind of disappeared, so you don't have to write them down anyway. For D, it's going to be a straight line across. So, it's going across happens at y equals to 7. So, you just have to write down y equals to 7 and that's it. So, there's no way actually you can do the slope-point form for that, okay? So those are your final answers. Thanks for watching.
