PLEASE HELP WILL GIVE BRAINLEIST

Answer:
(3, -4)
Step-by-step explanation:
For this problem you just need to find the distance between each of the x values and each of the y values.
The difference between -2 and -7 (-7 - -2) is -5, so the x coordinate of point B should be 3 (-2 - -5).
The difference between 2 and -1 (2 - -1) is 3, so the y coordinate of point B should be -4 (-1 - 3).
