Each term is only different by the x and the y coordinates right over here. The next term, and I'll write it, I'll go down so that we can combine like terms. This term over here squared is going to be y2 squared minus 2 times y2 times mx2 plus b plus mx2 plus b squared. Same exact thing up here, except now it was with x2 and y2 as opposed to x1 and y1. Then we're just going to keep doing that n times. We're just going to keep doing it n times. We're going to do it for the third, x3, y3, keep going, keep going, all the way until we get to this nth term over here.
