Answer:
(-5/2, -2)
Explanation:
The midpoint is halfway between two points. This makes it essentially the average. To find the midpoint add the x coordinates together and the y-coordinates together separately. Then divide each by 2.
x-coordinates
-12 + 7 = -5
-5/2
y-coordinates
5+-9 = -4
-4/2 = -2
So the midpoint is (-5/2, -2)
