If M (4.2) is the midpoint of AB and A (-5, -3), find the coordinates of B.

Given:

M(4,2) is the midpoint of AB and A(-5, -3).

To find:

The coordinates of B.

Solution:

Let the coordinates of point B are (a,b).

Midpoint formula:

M(4,2) is the midpoint of AB and A(-5, -3).

On comparing both sides, we get

And,

Therefore, the coordinates of point B are (13,7).
