There is a special "imaginary line" that astronomers like to draw between Mars and Jupiter (not the asteroids). What is that line, and how might it explain why terrestrial planets are much less massive than Jovian planets?

The special imaginary line is called Frost Line. Jovian Planets do not have solid surfaces and are made up of mostly gases. This is the reason why they are called gas giants. Jovain planets are located very far away from the sun d hence they re cooler.
