Plot the points and . Construct a rectangle where those two points are opposite vertices. Draw any line between the two points that:
1. Does not go past any side of the rectangle in any direction
2. Does not intersect any possible vertical line through the rectangle or cooincident with either of the vertical sides of the rectangle more than once.
The easiest thing to do is just draw a straight line between and including the two points.
