Question

What is the reflection image of R across the y-axis?

Answer 1

The reflection image of R across the y-axis is R'(3, 2)

Answer 2

The coordinates of image of R are (3,2). Therefore the correct option is 4.

Explanation:

If a figure reflected across the y-axis, then

`(x,y)\rightarrow (-x,y)`

From the given figure it is clear that the coordinates of R are (-3,2). So, the reflection image of R across the y-axis is

`R(-3,2)\rightarrow R'(3,2)`

The coordinates of image of R are (3,2). Therefore the correct option is 4.
