Question 995212: The midpoint of SR is (5,-11). One endpoint is S(3,5). What are the coordinates of point R?
Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! To go from one endpoint to the midpoint, notice we added two to the x-coordinate and subtracted 16 from the y-coordinate. We would do exactly the same to go from the midpoint to the other endpoint. Thus the other endpoint is
(5+2, -11-16) or (7, -27)
