Two rovers are exploring a planet. The system of equations below shows each rover's elevation y at time x. Without graphing these equations, what conclusion can you make about the system of equations? Use pencil and paper.
Rover 1. y = 1.2x - 6
Rover 2. y = 8.4x - 42
A. The system has exactly one solution.
B. The system has infinitely many solutions.
C. The system has no solution.
