Question

write the coordinates of the vertices after a reflection over the y - axis. r(, ) s(, ) t(, ) u(, )

Explanation:

Step1: Identify original coordinates

From the graph: $R(-4,9)$, $S(2,9)$, $T(2,4)$, $U(-4,4)$

Step2: Apply y-axis reflection rule

Reflection over y-axis: $(x,y)→(-x,y)$
$R(-4,9)→(4,9)$; $S(2,9)→(-2,9)$; $T(2,4)→(-2,4)$; $U(-4,4)→(4,4)$

Answer:

$R'(4,9)$, $S'(-2,9)$, $T'(-2,4)$, $U'(4,4)$
