A system of equations is given below.
 y = negative 2 x + one-fourth and y = negative 2 x minus one-fourth
 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.
