Answer:
(-5, 3)
Step-by-step explanation:
The coordinates of the midpoint are the averages of the endpoints.
-1.5 = (x + 2) / 2
-3 = x + 2
x = -5
6 = (y + 9) / 2
12 = y + 9
y = 3
Answer:
y = 7
Step-by-step explanation:

Add -4y and 6y

Move all terms not containing y to the right side of the equation.

Divide both sides by 2

Answer:
