Q (3,9) P(-1,5) --------------------- Let the other end point be (x,y) ---------------- Note: The coordinates of the midpoint are the average of the coordinates of the endpoints. --------------------- EQUATIONS: (3+x)/2 = -1 3+x=-2 x=-5 --------- (9+y)/2 = 5 9+y = 10 y = 1 -------------- Coordinates of the other end point (-5,1) ============= Plot the points to see if the answer makes sense ================ Cheers, Stan H.
