So let's think about what that means. So if the equation of this line right here is y is equal to mx plus b. And this just comes straight out of algebra 1. This is the slope of the line. And this is the y-intercept. This is actually the point 0b right here. What I want to do is I want to find, and that's what the topic of the next few videos are going to be, I want to find an m and a b.
