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, say $A=(5,3)$.

Step3: Calculate reflected - point coordinates

Using the rule, the reflection of $A=(5,3)$ across the $x -$axis is $(5, - 3)$.

Answer:

Plot the point with the same $x -$coordinate as point $A$ and the $y -$coordinate that is the negative of the $y -$coordinate of point $A$. For example, if $A$ is approximately at $(5,3)$, plot the point $(5,-3)$.
