Question

HELP PLEASE!!

Answer 1

Answer: 1/3

Step-by-step explanation:

We know that after dilation with scale factor k the coordinates of pre-image (x,y) map to (kx,ky) of the image.

From the given graph, the coordinate of A =(9,4) and the coordinate of A' (3,2)

Then $x = 9$ and $kx = 3$

$\Rightarrow k(9)=3\\\\\Rightarrow\ k=\frac{3}{9}\\\\\Rightarrow\ k=\frac{1}{3}$

Therefore, the scale factor of the dilation is 1/3.
