1. Answer:

    (25, 29)

   Step-by-step explanation:

   The midpoint formula can be solved to give an expression for one end point of a line segment in terms of the other end point and the midpoint.

   Formula

   The midpoint (M) of segment AB is found from …

     M = (A +B)/2

   Solving for B, we get …

     B = 2M -A

   Application

   For A(-9, -1) and M(8, 14), we find the end point B to be …

     B = 2(8, 14) -(-9, -1)

     B = (16 -(-9), 28 -(-1)) = (25, 29)

   The other end point is (25, 29.
