It's early in the evening, and you're standing in your back yard waiting for the stars to come out. Before long, you can see two stars in the sky. The equation of the line between you and Venus (which is actually a planet, but looks like a star) is y = 10x + 30. The equation of the line between you and Sirius is y = 9x + 40.
Which star is higher in the sky?
