Question

the figure below has a point marked with a large dot. first, reflect the figure across the x - axis. then, give the coordinates of the marked point in the original figure and the final figure. point in original figure: (,) point in final figure: (,)

Explanation:

Step1: Locate original marked point

Count grid units: x=4, y=7. So original point is $(4, 7)$.

Step2: Apply x-axis reflection rule

Reflection over x-axis: $(x, y) \to (x, -y)$. Substitute $x=4, y=7$: $(4, -7)$.

Answer:

Point in original figure: $(4, 7)$
Point in final figure: $(4, -7)$
