I'm just dividing numerator and denominator by delta x. Plus 6 plus delta x. So that is the slope of the secant line. So slope is equal to 6 plus delta x. That's this one right here. That's this reddish line that I've drawn right there. So if this number right here, if the delta x was 1, if these were the points 3 and 4, then my slope would be 6 plus 1.
