Answer:
(-1, -7)
Explanation:
You want the midpoint of segment AB with end points A(-3, -5) and B(1, -9).
Midpoint formula
The midpoint has coordinates that are the average of the end point coordinates:
M = (A +B)/2
M = ((-3, -5) +(1, -9))/2 = (-3+1, -5-9)/2
M = (-2, -14)/2 = (-1, -7)
The midpoint of AB is (-1, -7).

Additional comment
On the graph, you notice the points are 4 units apart horizontally, and 4 units apart vertically. Dividing each of those measures in half tells you the midpoint is 2 units horizontally and vertically from either end.
A +(2, -2) = (-3 +2, -5 -2) = (-1, -7) . . . . location of midpoint relative to A
B +(-2, 2) = (1 -2, -9 +2) = (-1, -7) . . . . . location of midpoint relative to B
