So if you use this line as a model, in 1995 the line would say that you're going to make 52,847. The actual data was a little bit off of that. It was a little bit higher, 53,807. So it was a little bit higher, but we're trying to get a line that gets as close as possible to all of this data. It's actually trying to minimize the distance, the square of the distance, between each of these points in the line. And we won't go into the math there. But it gave us this nice equation.
