The nice thing about this question is that due to the symmetric properties of a quadratic curve, the gradients are also symmetric.

Both the slopes have a gradient value of 11 at the same “height” y = 5, just that one of the slopes is going down (gradient is -11) while the other is going up (gradient is 11).
