Question

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

Explanation:

Step1: Recall reflection rule

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

Step2: Identify point A coordinates

Assume point $A$ has coordinates $(0, - 4)$ (from the graph).

Step3: Apply the rule

For point $A(0,-4)$, its reflection across the $x - axis$ is $(0,4)$ since $x = 0$ and $y=-(-4)=4$.

Answer:

Plot the point $(0,4)$ on the graph.
