Answer:
(c) (-3, 0) and (-5, 0)
Step-by-step explanation:
The given coordinates are -3 -(-5) = 2 units apart on the horizontal line y=-2.
Then the needed coordinates will be on the vertical lines x=-5 and x=-3, and will have y-coordinates that are different from -2 by 2: either -4 or 0.
The points that meet these requirements are (-3, 0) and (-5, 0).
