Question

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

Answer 1

15 is 3 times 5. The point (5, 0) is dilated to the point (15, 0) by using a factor of
  K = 3.

Answer 2

Answer:

The correct option is b) 3

Step-by-step explanation:

A dilation with the origin O (0, 0),

DO, K = (5, 0) (15, 0)

we need to determine the scale factor "K"

Since, 15 is 3 times of 5.

The point (5, 0) is dilated to the point (15, 0) by using a determine the scale factor of K = 3.

Therefore, the correct option is b) 3 .
