Reflection across the y axis the y coordinate values remains the same but the x coordinates value changes sign. For example
[tex](x,y)\rightarrow(-x,y)[/tex]
Therefore,
[tex]\begin{gathered} (6,8)\rightarrow(-6,8) \\ (1,1)\rightarrow(-1,1) \\ (0,3)\rightarrow(0,3) \\ (3,2)\rightarrow(-3,2) \end{gathered}[/tex]
Set D has an error.
