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 $(x_0,y_0)$. From the graph, if we estimate (assuming integer - like coordinates for simplicity), say $A=(5,4)$.

Step3: Apply the rule

The reflection of $A=(5,4)$ across the $x - axis$ is $(5, - 4)$.

Answer:

Plot the point with the same $x$ - coordinate as point $A$ and the $y$ - coordinate with the opposite sign of point $A$'s $y$ - coordinate. For example, if $A$ is at $(5,4)$, plot the point $(5,-4)$.
