Answer:
The answer to your question is (-5, 0)
Step-by-step explanation:
Data
Endpoint = (9, 0)
Midpoint = (2, 0)
Endpoint 2 = ?
Formula
Xm = (x1 + x2) / 2
Ym = (y1 + y2) / 2
-Solve for x2 and y2
X2 = 2Xm - x1
Y2 = 2Ym - y1
-Substitution
X2 = 2(2) - 9
Y2 = 2(0) - 0
-Simplification
X2 = 4 - 9 = -5
Y2 = 0 - 0 = 0
-Coordinates of the endpoint 2
(-5, 0)
