The correct answer is A. (x + 8, y - 4)
This is the correct answer because when going right on the x axis, means that you are adding or that it is positive. When going left on the x axis, means you are subtracting, or it is negative.
On the y axis, when going up, you are adding or it is positive. So when you are going down, means you are subtracting or it is negative.
I hope that this helps.
