The midpoint of AB is M(2,0). If the coordinates of A are (-3, 3), what are the coordinates of B?

Given:

M is the midpoint of AB.

M(2,0) and A(-3, 3).

To find:

The coordinates of point B.

Solution:

Midpoint formula:

Let the coordinates of point B are (a,b). Then, using the midpoint formula, we get

On comparing both sides, we get

And,

Therefore, the coordinates of point B are (7,-3).
