Question

Given a dilation with the origin O (0, 0), by observation determine the scale factor "k."

DO,K = (3, 2) ( 9, 6)
What is the scale factor K =

Answer 1

K=3.
the scale factor.
to get scale factor:
divide 9 by 3 (9/3) =3
or divide 6 with 2 ( 6/2) =3
Both should yied the same value

I general: Let the coordinates be (x,y)
=> original Coordinates = (x,y)
and Final coordinates = (kx, ky)
then the scal factor is k ,
