A system of equations is given below. y= -2x + 1/4 and y= -2x-1/4 Which of the following statements best describes the tivo lines?
They have the same slope but different intercepts, so they have no solution
They have the same slope but different 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 suintercept they have one solution
