The midpoint of overline AB is M(0, - 7) . If coordinates of A are (- 2, - 6) , what are the coordinates of B?

Given:

The midpoint of overline AB is M(0, - 7) .

The coordinates of A are (- 2, - 6).

To find:

The coordinates of point B.

Solution:

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

Midpoint formula:

The midpoint of overline AB is M(0, - 7). Using the midpoint formula, we get

On comparing both sides, we get

And,

Therefore, the coordinates of point B are (2,-8).
