Which are the coordinates of the midpoint of jk with endpoints j(-7, -1) and k(13, -6)?
a (6, -7)
b (-10, 5/2)
c (-13/2, 6)
d (3, -7/2)

The x coordinate of J is -7. The x coordinate of K is 13. The x coordinates add up to -7+13 = 6. Divide this result in half to get 6/2 = 3. Therefore, the midpoint has an x coordinate of 3.

The y coordinate of J is -1. The y coordinate of K is -6. The y coordinates add up to -1+(-6) = -7. Divide this result in half to get -7/2. Therefore, the midpoint has a y coordinate of -7/2.

This is why the final answer is choice D) (3, -7/2)

Itatchi hands down the best character
