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.
