Answer:

The constant rate of proportionality is r = 0.2

Step-by-step explanation:

We have an equation in the following format:

y = rx

In which r is the constant rate of proportionality.

To find r, we find a pair of x and y and replace.

8|1.6

This means that when x = 8, y = 1.6. So

y = rx

1.6 = 8r

8r = 1.6

r = 1.6/8

r = 0.2

The constant rate of proportionality is r = 0.2

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.
