Question

Which of the following is a transformation rule that translates a figure 4 units down and 1 unit to the right?

A. (x,y) → (x – 4, y + 1)
B. (x,y) → (x + 4, y - 1)
C. (x,y) → (x + 1, y + 4)
D. (x, y) + (x + 1, y - 4)

Answer 1

D

Explanation:

So when looking at this problem, its important to note that your X is your horizontal axis, and your Y is your vertical axis. So when moving left or right, you want to look at the x, so generally adding to X moves the point to the right, and subtracting from x moves the graph to the left. So for X, because you are looking at moving 1 unit to the right, you are going to want to add 1 (x+1), Then since y is your vertical axis, this will be your up or down factor. So its very similar if you are adding to y, you are moving up, but if you are subtracting from y, you are moving down. Therefore your final answer will be (x+1, y-4)

Answer 2

Your answer would be D
