(9, -1)

Step-by-step explanation:

Midpoint Formula:

Since we already have 1 endpoint and the midpoint, all we need to do is set the equation up to find the other endpoint:

12.5 = (16 + x)/2

25 = 16 + x

x = 9

-4 = (-7 + y)/2

-8 = -7 + y

y = -1

(9, -1)

Step-by-step explanation:

(16 + x)/2= 12.5

16 + x = 25

x = 9

(-7 + y)/2 = -4

-7 + y = -8

y = -1
