A segment has a midpoint at (2,-7) and an endpoint at (8,-5). What are the coordinates of the other endpoint?

(-4,-9)

Step-by-step explanation:

Given a segment AB with endpoints with coordinates

A:

B:

The coordinates of the midpoint M of the segment AB are given by:

(1)

In this problem, we know that:

- The midpoint of the segment AB has coordinates

- One of the endpoint of the segment has coordinates

So we  can find the coordinates of the other endpoint A by re-arranging eq.(1) above:

And substituting, we find:

So, the coordinates of the other endpoint are (-4,-9).
