Exercise 17 Page 384

For l to intersect P at only one point, l cannot be contained within P.

Example Solution:

Practice makes perfect

Let's start by sketching an arbitrary plane P.

Since line l is to intersect P at only one point, l cannot be completely contained within P. If the line was in the plane, they would intersect at infinitely many points. Thus, we can sketch l as a line that intersects plane P at exactly one point by letting it approach P at an angle.
