Question

A is (-2,-5) A’is a glide relection where the translation is (x,y) Is(x+7,y) the line of reflection is y=2 What are the coordinates of A’

Answer 1

Answer: A' (5,9)

Step-by-step explanation:

1. You have that the translation is $(x,y)$⇒$(x+7,y)$ and the coordinates of A is (-2,5). Then:

$A(-2+7,-5)$⇒$A(5,-5)$

2. As you can see, -5 is 7 units below of the line of reflection $y=2$, therefore, you can know the coordinates of A' as following:

$A'(5,7+2)\\A'(5,9)$

3. Then, the coordinates of A' is (5,9)
