The midpoint of AB is M(0, -4). If the coordinates of A are (-8, -7), what are the coordinates of B?

Question

this is my geometry classwork, need help asap

Answer 1

Let B = (x, y)

Using the midpoint formula, we have: (x + (-8)) / 2 = 0 and (y + (-7)) / 2 = -4.

Solve for x and y.

Answer 2

One posting of a problem is sufficient.
