    you just have a horizontal line on the y-axis in your graph.. it's not C and it's not D. It's just .. well it's a positive number. I'll leave it at that, but I'll give you an example whenever we have x = 3 that means that x =3 only and it will always be 3....we don't consider a y anything, and we have a vertical line. Draw a vertical line parallel to the y-axis, and the equation doesn't depend on y |dw:1434094705268:dw| similarly, if we have y = 3 that means y=3 only and we don't consider a x anything. We end up with a horizontal line. As in draw a horizontal line parallel to the x-axis...the equation doesn't depend on x. |dw:1434094806264:dw|

    |dw:1434095133148:dw| y = 2x is x y =2x 0 0 1 2 2 4 3 6 and y=-2x is a reflection of the graph y=2x

    http://www.wolframalpha.com/input/?i=graph++y%3D2x%2Cy%3D-2x I only graphed the positive portion in my drawing because I know that graphs drawn on here is not to scale and messy
