### Example Question #12 : Coordinate Geometry

The points A, B, and C reside on a line segment. *B *is the midpoint of *AC.* If line AB measures 6 units in length, what is the length of line *AC*?

**Possible Answers:**

**Correct answer:**

Explanation:

If *B *is the midpoint of *AC, *then *AC *is twice as long as *AB. *We are told that *AB*=6.

The diagram shows six units between points *A* and *B,* with *B* as the midpoint of segment *AC*. Therefore segment *BC* is also six units long, so line *AC* is twelve units long.
