Answer:
B(8, -6)
Explanation:
You want the coordinates of B if A = (-8, 8) and the midpoint of AB is (0, 1).
Midpoint
The midpoint coordinates are the average of the endpoint coordinates. If the midpoint is M, we have ...
M = (A +B)/2
Solving for B gives ...
2M -A = B
2(0, 1) -(-8, 8) = (2·0 +8, 2·1 -8) = (8, -6)
The coordinates of B are (8, -6).
