Question

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

DO, K = (5, 0) (15, 0)
What is the scale factor K?

A. 1/3
B. 3
C. -3

Answer 1

If you are going from (5,0) to (15,0)

then you solve 5k = 15 for k to get your answer

-------------------------------------------------------

If you are going from (15,0) to (5,0)

then you solve 15k = 5 for k to get your answer

Answer 2

So then it would be 3?

Answer 3

that's if you start with (5,0) and end up with (15,0), yes

Answer 4

notice how (15,0) is 3 times further away from O(0,0) as compared to (5,0)

Answer 5

so then it would be -3 right?

Answer 6

how are you getting -3?

Answer 7

its going from 5,0 to 15,0 so it would just be 3?

Answer 8

yep

Answer 9

Oh okay I see. Thank you so much!
