Question

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

Explanation:

Step1: Identify coordinates of A

Point A is at $(-1, -7)$

Step2: Apply x-axis reflection rule

For reflection across x-axis, $(x,y)\to(x,-y)$.
New coordinates: $(-1, -(-7))=(-1,7)$

Answer:

The reflected point is at coordinates $\boldsymbol{(-1, 7)}$, which is the point 1 unit left of the y-axis and 7 units above the x-axis on the grid.
