Answer 1

(9, -1)

Explanation:

(16 + x)/2= 12.5

16 + x = 25

x = 9

(-7 + y)/2 = -4

-7 + y = -8

y = -1

Answer 2

(9, -1)

Explanation:

Midpoint Formula:
`((x1+x2)/(2), (y1+y2)/(2) )`

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
