Question

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: Identify coordinates of J

Point $J$ is at $(2, 4)$

Step2: Apply y-axis reflection rule

For reflection over y-axis, $(x,y)\to(-x,y)$. So $J' = (-2, 4)$

Answer:

The reflected point $J'$ is at coordinates $(-2, 4)$ (plotted 2 units left of the y-axis, 4 units above the x-axis)
