Question

reflections
if $p = (1, 3)$ find $p$ after $r_{x=2}(p)$
$p = (?, )$

Explanation:

Step1: Find horizontal distance to line

Distance = $2 - 1 = 1$

Step2: Calculate new x-coordinate

New $x = 2 + 1 = 3$

Step3: Keep y-coordinate unchanged

Original $y = 3$, so new $y = 3$

Answer:

$P' = (3, 3)$
