Question

give the coordinates of the vertices of quadrilateral ghij under a dilation about the origin with scale factor of 3.
g (11,5)
h (-3,5)
i (-7,-4)
j (4,-7)
show your work here

g =

h =

i =

j =

Explanation:

Step1: Dilate G by scale factor 3

$G'(11×3,5×3)=(33,15)$

Step2: Dilate H by scale factor 3

$H'(-3×3,5×3)=(-9,15)$

Step3: Dilate I by scale factor 3

$I'(-7×3,-4×3)=(-21,-12)$

Step4: Dilate J by scale factor 3

$J'(4×3,-7×3)=(12,-21)$

Answer:

G'=(33,15), H'=(-9,15), I'=(-21,-12), J'=(12,-21)
