If R is zero, that means that a line isn't describing the relationships well at all. Now in our situation here, not to use a pun, in our situation here, our R is pretty close to one, which means that a line can get pretty close to describing the relationship between our Xs and our Ys. So for example, I'm just going to try and hand-draw a line here, and it does turn out that our least squares line will always go through the mean of the X and the Y. So the mean of the X is two, mean of the Y is three. We'll study that in more depth in future videos. But let's see, this actually does look like a pretty good line. So let me just draw it right over there.
