I could do it maybe clearer showing it right over here. Whatever the slope is right over here, it's the exact negative of whatever the slope is at a symmetric point on the other side. So if on the other side, the slope is right over here, over here, it's going to be the negative of that. So it's going to be right over there. And then the slope just gets more and more and more negative. Right over here, the slope is a positive 1. Over here, it's going to be a negative 1.
