Forgive my ignorance, but if the moon orbits around the earth (ie not geostationary), how can the end of a line attached to the moon stay in one place above the earth?

The moon is tidally locked to earth, meaning it rotates at such a speed that the same side is always facing earth. (This is also why the moon can have a "dark side")

It usually takes millions of years of tidal forces from a planetary body acting upon its satellite for the latter to be tidally locked to the former.

Thank you. I understand that part, but is the line supposed to be at the same point above the earth?

No. It wanders around the earth every 28 days.
