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 $(- 9,0)$ (estimated from the graph).

Step3: Apply reflection rule

Using the rule $(-x,y)$, for point A$(-9,0)$, the reflected point has coordinates $(9,0)$.

Answer:

Plot the point $(9,0)$ on the graph.
