A system of equations is given below.
y=-3x+6 and y=6-3x
Which of the following statements best describes the two lines?
They have different slopes and different y-intercepts, so they have no solution.
O They have different slopes and different y-intercepts, so they have one solution.
They have the same slope and the same y-intercept, so they have no solution.
O They have the same slope and the same y-intercept, so they have infinitely many solutions.
