First, we need to locate the points J, A and R:
J is in red, A is in green and R is in purple.
Now to make a reflection across the y-axis, we need to multiply the x-coordinate of each point by (-1):
[tex]\begin{gathered} J(2,5)\Rightarrow J^{\prime}(-2,5) \\ A(6,6)\Rightarrow A^{\prime}(-6,6) \\ R(4,2)\Rightarrow R^{\prime}(-4,6) \end{gathered}[/tex]
And we get:
Which is the reflection across the y-axis
