Question

The midpoint of AB is M (3,-2). If the coordinates of A are (1, -3), what are the

coordinates of B?

Answer 1

The coordinate of endpoint B is (5, -1).

Explanation:

The distance from A to M and the distance from M to B are equal in length if point M (3, -2) is the exact midway.

Start by finding the distance between the x's of points A and M.

The distance from 1 to 3 is +2.

Then, find the distance between the y's of points A and M.

The distance from -3 to -2 is +1.

Using the midpoint's coordinates, use the two values you found to locate endpoint B's coordinates.

x = (3 + 2), y = (-2 + 1)

x = 5, y = -1.

To conclude, the coordinate of endpoint B is (5, -1).
