As the lead structural engineer on a large government project, you have to plot out the paths of both the east-bound and west-bound directions of a new part of the Eisenhower Interstate Highway system. Since the site for the new road is nice and flat, the two directions of travel will go in straight, parallel lines.
On your mapping software, the centerline of the east-bound lanes run along a line defined by y=\frac{1}{9}x-12. The west-bound lanes should run parallel to the east-bound lanes, but separated by a big enough gap that the centerline of the west-bound lanes passes through the point (18, 14).
Which of the following points will also be in center of the path of the west-bound lanes?

(-36, 10)

(0, 10)

(72, 20)

(40, 20)
