Okay. So we are talking about going down 4 units and going to the left 5 units. When we go down, we subtract outside of the parenthesis. D is out, because we go down, not up. C is eliminated, because that is not the amount we are going down. When it comes to horizontal transitions, adding means we move to the left, subtracting means we move to the right. In this case, we move to the left 5 units, so we add 5 inside the parenthesis. That also eliminates A. The only answer that works is B. The answer is B.
