Find the coordinates of the missing endpoint if W is the MIDPOINT of XY.

W(4,-2) X(7,-4)

The coordinates of the missing point if W is the midpoint of XY is .

Explanation:

From Linear Algebra we define the location of midpoint by the following expression:

(1)

Where:

, - Endpoints of the line segment, dimensionless.

- Midpoint, dimensionless.

If we know that and , then the location of the point Y is:

The coordinates of the missing point if W is the midpoint of XY is .
