Answer:

(8, -1)

Step-by-step explanation:

The midpoint given two points (x1, y1) and (x2, y2) is:

([x1 + x2] / 2, [y1 + y2] / 2)

We have the point (x1, y1) as (-8, -7) and the midpoint as (0, -4). We can plug them in and create two equations, one to find x2, and another for y2.

0= [-8 + x2] / 2

0 = -8 + x2

x2 = 8

-4 = [-7 + y2] / 2

-8 = -7 + y2

y2 = -1

Therefore, point B is (8, -1)
