Question

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

Explanation:

Step1: Identify coordinates of A

Point A is at $(8, 4)$.

Step2: Apply x-axis reflection rule

For reflection across x-axis, $(x,y) \to (x,-y)$.
New coordinates: $(8, -4)$.

Answer:

Plot the point at $(8, -4)$ on the coordinate grid.
