Question

write the coordinates of the vertices after a reflection over the y-axis.
k( , )
l( , )
m( , )

Explanation:

Step1: Identify original vertices

Original coordinates: $K(9,0)$, $L(9,5)$, $M(6,-2)$

Step2: Apply y-axis reflection rule

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

• $K'$: $(-9, 0)$
• $L'$: $(-9, 5)$
• $M'$: $(-6, -2)$

Answer:

$K'(-9, 0)$
$L'(-9, 5)$
$M'(-6, -2)$
