Asystem of equations is given below. y= 2x-3 and y = - 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.
