We went from negative one to negative three is equal to negative two. So slope, which is change in y over change in x, rise over run, is equal to seven over negative two, or, oh, actually, let me, no, I did it the other way around. Change in y is negative two over seven. So negative two sevens. And that's all it is. Now, you could kind of think of it in kind of the more fancy sense, but you're gonna get the exact same answer if you said, oh, well, look, the average rate of change of f on the interval, well, the rate of change of f is f prime, f prime of x. That is the rate of change of f at any point x.
