Question

using the pencil, plot the reflection of point a across the y - axis.

Explanation:

Step1: Recall reflection rule

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

Step2: Identify point A coordinates

Assume point $A$ has coordinates $(2, - 6)$.

Step3: Apply the rule

The reflected point across the $y -$axis will have coordinates $(-2,-6)$.

Answer:

Plot the point $(-2,-6)$ on the graph.
