Question

The midpoint of overline AB is M(2, -2) If the coordinates of A are (-2, 1), what are the coordinates of B?

Answer 1

(6, -5)

Explanation:

Midpoint :

• (2, -2) = (x - 2 / 2, y + 1 / 2)

Equations formed :

1. x - 2 / 2 = 2

• x - 2 = 4
• x = 6

2. y + 1 / 2 = -2

• y + 1 = -4
• y = -5

Coordinates of B : (x, y)

• (6, -5)
