And I will switch colors just to ease the monotony. So my slope of my tangent of my secant line, the one that goes through both of these, is going to be equal if you divide the numerator and denominator. This becomes 6. 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.
