Answer:
The correct option is <u>b) 3</u>
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 <u>b) 3</u> .
