We're going to actually do an example of this in a few seconds. Divided by the mean of x squared minus the mean of the x squared's. And if this looks a little different than what you see in your statistics class or your textbook, you might see this swapped around. If you multiply both the numerator and the denominator by negative 1, you could see this written as the mean of the xy's minus the mean of x times the mean of the y's, all of that over the mean of the x squared's minus the mean of the x's squared. These are obviously the same thing. They're just multiplying the numerator and the denominator by negative 1, which is the same thing as multiplying the whole thing by 1. And of course, whatever you get for y, oh sorry, whatever you get for m, you can then just substitute back in this, back over here to get your b.
