Question

RST is dilated about the origin, O, to create ΔR'S'T'. Point R is located at (3, 9), and point R' is located at (1.2, 3.6). Which scale factor was used to perform the dilation?

Answer 1

Are there any answer choices?

Answer 2

no I have to fill it in myself...

Answer 3

To find the scale factor, divide the first coordinates by the second
coordinates:
x-coordinates:
3÷1.2=2.5
y-coordinates:
9÷3.6=2.5
The scale factor is:
?

0.4

Answer 5

No, it's not 0.4

Answer 6

It's 2.5

Answer 7

it is 0.4... that's the answer I was given...

Answer 8

By who?

Answer 9

To find the scale factor, divide the first coordinates by the second coordinates:
x-coordinates:
3÷1.2 =2.5
y-coordinates:
9÷3.6=2.5
The scale factor is:
2.5
