Answer 1

Answer:  D)   y+3

==========================================================

Explanation:

Point A is located at (3,1). Point A' is located at (-5,4)

To move from A to A', we'll do two things:

• Move 8 units to the left
• Move 3 units up

The "8 units to the left" portion has us go from x to x-8

The "3 units up" part involves y becoming y+3

So that's how we get the translation rule $(x,y) \to (x-8,y+3)$. The x-8 portion is already filled in for us. The missing part is y+3 which is the final answer (choice D).

Let's try this translation rule on point B to see if we arrive at the proper location of B'

B is at (2,6) which means

$(x,y) \to (x-8,y+3)\\\\(2,6) \to (2-8,6+3)\\\\(2,6) \to (-6,9)$

which matches up what the diagram shows. I'll let you verify that the rule also works for point C.
