The rule for the reflection is ry-axis [tex](x,y) \to (-x,y)[/tex]
How to determine the rule?
From the figure, we can see that the shape is flipped over the y-axis
This means that the reflection is across the y-axis.
The reflection rule over the y-axis is:
[tex](x,y) \to (-x,y)[/tex]
Hence, the rule for the reflection is ry-axis [tex](x,y) \to (-x,y)[/tex]
