Question

1. Which rule describes a translation that is 8 units to the right and 2 units up?

(x,y) → (X + 8, Y - 2)
(x,y) → (X + 8, y + 2)
(x,y) → (X-8, y + 2)
(x, ) - (x - 8, Y - 2)

Answer 1

3rd one because it makes sense

Answer 2

The answer is the second rule: (x,y) --> (x+8, y+2).

Explanation:

If you look at a graph, positive "x" is to the right, and negative "x" is to the left. Positive "y" is up, and negative "y" is down. Knowing this, if the problem is asking you how to describe moving 8 units to the right and 2 units up, then you know that it wants both a positive "x" and a positive "y".
