C is the answer because the X factors can’t repeat
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)
Answer:

Hence, 16.8 miles is your answer
4. 54 + 63 + 54=171
5. 3+3+75=81
6. 20+68=89
7. 120+180=300 x 1.48=$444
W^2-3w=350
w^2-3w+2.25=352.25
(w-1.5)^2=352.25
w-1.5=±√352.25
w=1.5±√352.25
(w+1.5+√352.25)(w+1.5-√352.25)
