Asystem of equations is given below. y=1/2x3 and y=-1/2x-3 which of the following statements best describes the two lines? they have the same slope but different y-intercepts, so they have no solution. they have the same slope but different y-intercepts, so they have one solution. they have different slopes but the same y-intercept, so they have no solution. they have different slopes but the same y-intercept, so they have one solution.
