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