Question

write the coordinates of the vertices after a reflection over the y-axis.

Explanation:

Step1: Identify original coordinates

Original vertices: $Q(6, 0)$, $T(6, 2)$, $S(9, 2)$, $R(9, 0)$

Step2: Apply y-axis reflection rule

For a point $(x,y)$, reflection over y-axis is $(-x,y)$.

• $Q': (-6, 0)$
• $T': (-6, 2)$
• $S': (-9, 2)$
• $R': (-9, 0)$

Answer:

$Q'(-6, 0)$, $T'(-6, 2)$, $S'(-9, 2)$, $R'(-9, 0)$
