Question

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

Explanation:

Step1: Identify coordinates of A

Point A is at $(7, 3)$

Step2: Apply y-axis reflection rule

For reflection over y-axis, $(x,y) \to (-x,y)$. So $(7,3) \to (-7, 3)$

Answer:

The reflected point is at $(-7, 3)$ (plot this point on the grid at x=-7, y=3)
