Answer:
The answer is A
Step-by-step explanation:
Midpoint formula: (x1 + x2) / 2, (y1 + y2) / 2
In this case, we already have the midpoint, so one of the x and one of the y values are unknown, whereas the sum is not.
(-1 + x) / 2 = 5, (3 + y) / 2 = -2
For both equations multiply both sides by 2
-1 + x = 10, 3 + y = -4
x = 11, y = -7
Rewrite as coordinates.
(11, -7)
