Let X, Y, and Z be points such that \(\frac{XZ}{XY} = \frac{ZY}{XY} = \frac{1}{2}\). If Y=(1,7), Z=(-1,-7), then what is the sum of the coordinates of X?

by drawing a graph and using some inspection, you see that z is the midpoint of y and x, so the coordinates of x are (-3, -21), and the sum of coordinates is -24.

Do you have to put “HOPE THIS HELPED!” in every post?

Every kid on here puts that on their answers.

We know you hope that, that’s why you answered the question.
