Your answer would be Parallel Lines.18 divided by a certain number (I'm sure you could discover this on your own) equals that of 6. Let me know if this helps, and if it was the correct answer
B/parallel lines. This is because: equation a) y=-2x+6 equation b) 3y=-6x+18 or if you divide by 3 on both sides y=-2x+6 (so actually they're effectively the same line)
