Question

What is the scale factor used to create the dilation?

Answer 1

Answer: 2

Explanation:

Pre-Image:

- Length - 3

- Width - 4

Image:

- Length - 6

- Width - 8

6 / 3 = 2

8 / 4 = 2

Scale factor is 2.

So the answer is C.

Answer 2

The scale factor is 2

Explanation:

The scale factor of the dilation can be found using the formula;

`k=(Image\:length)/(Corresponding\:object\:length)`

This implies that;

`k=(|A'E'|)/(|AE|)`

We count the corresponding boxes to get each length to be;

`k=(6)/(2)`

simplify to get;

`k=2`

The scale factor must be positive because the image is to the right of the object and it is not inverted

The correct answer is C
