Answer:
(-3/2, 0)
Explanation:
You want the midpoint of line segment AB with end points A(-5, 5) and B(2, -5).
Midpoint
The midpoint of a line segment has coordinates that are the average of the end point coordinates.
M = (A +B)/2
M = ((-5, 5) +(2, -5))/2 = (-5+2, 5-5)/2 = (-3, 0)/2
M = (-3/2, 0)
The midpoint of the line segment is (-3/2, 0).
