Question

give the coordinates of the dilation.

1. $d_5(\triangle pqr)$ for $p(1, -3)$, $q(-5, -4)$, $r(6, 2)$

Explanation:

Step1: Dilate point P by scale 5

Multiply each coordinate of $P(1, -3)$ by 5:
$P'(1\times5, -3\times5) = (5, -15)$

Step2: Dilate point Q by scale 5

Multiply each coordinate of $Q(-5, -4)$ by 5:
$Q'(-5\times5, -4\times5) = (-25, -20)$

Step3: Dilate point R by scale 5

Multiply each coordinate of $R(6, 2)$ by 5:
$R'(6\times5, 2\times5) = (30, 10)$

Answer:

$P'(5, -15)$, $Q'(-25, -20)$, $R'(30, 10)$
