Heather writes the equations below to represent two lines drawn on the coordinate plane.–6x + 18y = 0 4x – 12y = 20

A
The equation has no solution; therefore, the system of equations has no solution.
B
The equation has a solution at (0, 60); therefore, the system of equations has a solution at (0, 60).
C
The equation has infinite solutions; therefore, the system of equation as infinite solutions.
D
The equation has a solution at (0, 0); therefore, the system of equations has a solution at (0, 0).
