Question

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

Explanation:

Step1: Identify coordinates of A

Point A is at $(4, 6)$

Step2: Apply y-axis reflection rule

For reflection over y-axis, $(x,y) \to (-x,y)$. So $(4,6) \to (-4,6)$

Step3: Plot the new point

Mark the point at $x=-4, y=6$ on the grid.

Answer:

The reflection of point A across the y-axis is the point at coordinates $(-4, 6)$, which is plotted 4 units left of the y-axis and 6 units above the x-axis.
