Answer:

The coordinates of B are (-1, -5).

Explanation:

Since the x-coodinate of M is 2 greater than that of B (note that -3 = -5 + 2), the x-coordinate of B is found by adding 2 to -3, obtaining -1. The y-coordinate of M is -3, which is 2 less than the y-coordinate of A; Thus, the y-coordinate of B is 2 less than -3, that is, -5.

The coordinates of B are (-1, -5).
