And I'll let you think about that a little bit more. But already, this is actually the two points that lie on the line. So both of these on the line. Both of these on the best fitting line, based on how we're measuring a good fit, which is the square distance. These are on the line that minimize that square distance. What I'm going to do in the next video, this is turning into like a six or seven video saga on trying to prove the best fitting line, or finding the formula for the best fitting line. But it's interesting.
