Question

Are the graphs of the lines in the pair parallel? Y=6x + 9 27x - 3y= -81

Answer 1

No, the graphs of the lines are not parallel because if you simplify 27x-3y=-81, you get y=9x+27, and in order to have the lines parallel, both equations must have the same "m" in y=mx+b. 6 and 9 do not equal, so no they are not parallel.
