Well, the slope of this right over here, this has slope 1 continuously, or it has a constant slope of 1. Slope is equal to 1 no matter what x is, it's a line. And for a line, the slope is constant. So over here, the slope is indeed 1. If you go to this point over here, the slope is indeed 1. If you go over here, the slope is indeed 1. So we got a pretty valid response there.
