In the plane rectangular coordinate system, the image of a function is a line segment AB and ab ∥ X axis. Given that the coordinate of point a is (2. - 1) AB = 5, then the coordinate of point B is?

In the plane rectangular coordinate system, the image of a function is a line segment AB and ab ∥ X axis. Given that the coordinate of point a is (2. - 1) AB = 5, then the coordinate of point B is?

The coordinates of point B are (7, - 1) or (- 3, - 1)
