Question

The midpoint of segment AB is (-2, 5). The coordinates of point A are (-7, 3). Find the coordinates of point B.

Answer 1

The coordinates of point B are (3, 7).

Explanation:

Mid point of AB = (-2. 5) = ( x - 7)/2 , (y + 3)/2 where (x, y) are the coordinates of point B.

Therefore (x - 7)/2 = -2 and 5 = (y + 3)/2.

x - 7 = -4 so x =3 and y + 3 = 10 so y = 7.
