Answer:
(2, -1)
Step-by-step explanation:
Points B and C are both at -1 on the x-axis, meaning they form the bottom side of the rectangle. This means A and D form the top side of the rectangle, and because A is at 2 on the x-axis, then so is D.
Points A and B are both at -5 on the y-axis, meaning they form the left side of the rectangle. This means that C and D form the right side, and because C is at -1 on the y-axis, then so is D.
Combining this information tells you that D has the coordinates (2, -1).
