Question

reflections
if $p = (-3, 4)$ find $p$ after $r_{y-axis}(p)$
$p = (?, \square)$

Explanation:

Step1: Recall y-axis reflection rule

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

Step2: Apply rule to $P=(-3,4)$

Substitute $x=-3$, $y=4$: $-x = -(-3) = 3$, $y$ remains $4$.

Answer:

$P'=(3, 4)$
