    yes they are parallel if you graph them.

    gradient = rise/run therefore, the gradient for x=2 is 0/2=0 and the gradient for x=4 is 0/4 = 0 hence both lines are parallel

    http://www.wolframalpha.com/input/?i=x%3D2+and+x%3D4 as you can see in the graph the lines are parallel to each other
