A segment has a midpoint at (2, -7) and an endpoint at (8, -5).
What are the coordinates of the other endpoint?
Notice that the midpoints are the average of the coordinate.
the other endpoint (x,y) coordinates will be
2=%288%2Bx%29%2F2
4=8%2Bx
x=-4
-7=%28-5%2By%29%2F2
-14=-5%2By
-14%2B5=y
-9=y
the other endpoint is at (x,y)=(-4,-9)
