The two endpoints we have are (-1,7) and (3,-3).
And we need to find the midpoint.
Step 1. Label the given coorfinates as (x1,y1) and (x2,y2):
Step 2. Use the midpoint formula:
Substituting the values for x1, x2, y1, and y2 that we found in step 1:
Step 3. Solve the resulting operations to find the coordinates of the midpoint:
Solving the divisions:
The midpoint is (1,2).
Answer: (1,2)
