Answer:
Explanation:
The difference between the x coordinates is 6, (difference between -3 and 3). Half of 6 is 3. Add this to the lowest value (-3) to get to zero.
Repeating the exercise for the Y coordinates we get a difference of 0 (there's no difference between the values 5 & 5). So adding this difference (0) to the lowest value (5) we get 5 still.
So the midpoint is (0,5)
