Explanation:

Step1: Recall reflection rule

When a point $(x,y)$ is reflected over the $y -$axis, the transformation rule is $(x,y)\to(-x,y)$. The $x -$coordinate changes sign and the $y -$coordinate remains the same.

Answer:

When a point is reflected over the $y$-axis, the $x$ - coordinate changes sign. If the coordinates of $J$ are $(x,y)$, the coordinates of $J'$ are $(-x,y)$.
