Question

write the coordinates of the vertices after a translation 8 units down.
b(□,□)
c(□,□)
d(□,□)
e(□,□)

Explanation:

Step1: Identify original coordinates

Original vertices: $B(-7, 5)$, $C(3, 5)$, $D(3, 7)$, $E(-7, 7)$

Step2: Apply translation rule

Translate 8 units down: subtract 8 from each $y$-coordinate.
For $B'$: $(-7, 5-8)=(-7, -3)$
For $C'$: $(3, 5-8)=(3, -3)$
For $D'$: $(3, 7-8)=(3, -1)$
For $E'$: $(-7, 7-8)=(-7, -1)$

Answer:

$B'(-7, -3)$
$C'(3, -3)$
$D'(3, -1)$
$E'(-7, -1)$
