There are 8 choices for the first painting on the wall, 7 choices for the second, and so on, down to three choices for the sixth. Our result is thus 8*7*6*5*4*3=20,160. C is the correct answer.
The question asks for a vertical line, and if it is vertical, it cannot be y = ... because that is horizontal. We also know it passes through the x-coordinate of -4, so the answer is x = -4.
Answer:
