Just like that. So this is a slope of the secant line. We still haven't answered what the slope is right at that point. But maybe this will help us get there. So if we simplify this, so let me write it down like this. The slope of the secant, let me write that properly. The slope of the secant line is equal to the value of the function at this point, f of x naught plus h, minus the value of the function here, minus f of x naught.
