match the system of equations to the number of solutions it has
infinite solutions , no solutions, one solution
responses:
y=5x+7 3y-15x=18
x-2y=6 3x-6y=18
y=3x+6 y= -1/3 x -4
y=2/3x -1 y=2/3x -2
y=5x+7 3y-15x=18 → one solution
x-2y=6 3x-6y=18 → infinite solutions
y=3x+6 y= -1/3 x -4 → no solutions
y=2/3x -1 y=2/3x -2 → one solution
