Question

the point j is plotted on the coordinate grid below. plot the point j, the reflection of j over the y - axis. click on the graph to plot a point. click a point to delete it.

Explanation:

Step1: Recall reflection rule

The rule for reflecting a point $(x,y)$ over the $y -$axis is $(-x,y)$.

Step2: Identify point J coordinates

From the graph, assume point $J$ has coordinates $(4, - 5)$.

Step3: Apply reflection rule

For point $J(4,-5)$, when reflected over the $y -$axis, the $x$ - coordinate changes sign. So the new point $J'$ has coordinates $(-4,-5)$.

Answer:

Plot the point $(-4,-5)$ on the graph.
