Answer: choice C
(5/2, 3)
===========================================================
Focus on the x coordinates for now.
Add them: 2+3 = 5
Divide in half: 5/2 = 2.5
The x coordinate of the midpoint is 5/2 in fraction form.
This narrows the answer between C and D.
------------
Repeat those steps for the y coordinates:
Add: -1+7 = 6
Divide in half: 6/2 = 3
The y coordinate of the midpoint is 3
------------
The midpoint is located at (5/2, 3) which points us to choice C as the final answer.
