Question

The midpoint of overline AB is M(-4, 0)M If the coordinates of A are (-6, 6) what are the coordinates of B?

Answer 1

(-2, -6)

Explanation:

Equating A and B to the Midpoint (M) :

• (-4, 0) = (-6 + x / 2, 6 + y / 2)

Equations formed :

1. -6 + x / 2 = -4

• -6 + x = -8
• x = -2

2. 6 + y / 2 = 0

• 6 + y = 0
• y = -6

Midpoint : (x , y)

• (-2, -6)
