Question

given l(0, 5), m(10, -10), & n(-5, 0), give the coordinates of the following images. 9. (x, y) → (3x, 3y) l ( , ) m ( , ) n ( , )

Explanation:

Step1: Scale L's coordinates

For $L(0,5)$, compute $(3\times0, 3\times5)$

Step2: Scale M's coordinates

For $M(10,-10)$, compute $(3\times10, 3\times(-10))$

Step3: Scale N's coordinates

For $N(-5,0)$, compute $(3\times(-5), 3\times0)$

Answer:

$L'(0, 15)$
$M'(30, -30)$
$N'(-15, 0)$
