Heather writes the equations below to represent two lines drawn on the coordinate plane.
 –6x + 18y = 0
 4x – 12y = 20
 After applying the linear combination method, Heather arrived at the equation 0 = 60. What conclusion can be drawn about the system of equations?
 The equation has no solution; therefore, the system of equations has no solution. 
 The equation has a solution at (0, 60); therefore, the system of equations has a solution at (0, 60).
 The equation has infinite solutions; therefore, the system of equation as infinite solutions.
 The equation has a solution at (0, 0); therefore, the system of equations has a solution at (0, 0).
