It would look like that, where this is our coordinate x naught. f of x naught. And up here is our coordinate for this point, which would be the x-coordinate would be x naught plus h. And the y-coordinate would be f of x naught plus h. Just whatever this function is, we're evaluating it at this x-coordinate. That's all it is. So these are the two points. So maybe a good start is just say, hey, what is the slope of this secant line? And just like we did in the previous example, you find the change in x.
