Question

write the coordinates of the vertices after a translation 3 units left.
k (□, □)
l (□, □)
m (□, □)

Explanation:

Step1: Identify original coordinates

Original vertices: $K(-7, 2)$, $L(-7, 10)$, $M(-6, 2)$

Step2: Apply left translation rule

Subtract 3 from each $x$-coordinate:
For $K'$: $x=-7-3=-10$, $y=2$
For $L'$: $x=-7-3=-10$, $y=10$
For $M'$: $x=-6-3=-9$, $y=2$

Answer:

$K'(-10, 2)$
$L'(-10, 10)$
$M'(-9, 2)$
