Line segment AB has an endpoint, A, located at , and a midpoint at . What are the coordinates for point B of segment AB?

Solve each problem and decide which is the best of the choices given.

What is the distance between the points and on a standard coordinate plane?

Point A is (5, 7). Point B is (x, y). The midpoint of AB is (17, –4). What is the value of B?

The midpoint of line segment AB is (2, -5). If the coordinates of point A are (4, 4), what are the coordinates of B?
