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)

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)
