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. Now we can use this nice equation to predict things. If we say that this is a good model for the data, let me bring this down a little bit, let's try to answer our question. So we drew a scatter plot, really Excel did it for us.
