Question

A line segment with endpoints Q(-3, 2) and R(-1, -5) is dilated with the origin as the center of dilation. The resulting endpoints are Q’(-9, 6) and R’(-3, -15). What is the scale factor?

a- 1/3
b- 1/9
c- 9
d- 3

Answer 1

plz anyone help

Answer 2

@goformit100 can you help

Answer 3

plzzz

Answer 4

i am not so sure of this question
i think, if i solved it correctly then b- 1/9 is the answer

Answer 5

Hi again.

I am sure. Answer is d-3
yes it should be.

Answer 6

how did you get that

Answer 7

Who me ?

Answer 8

i think it's b

Answer 9

yes

Answer 10

@Shayaan_Mustafa yes you

Answer 11

OK as you can see endpoints after dilation are Q'(-9,6) which is the 3 multiple of Q(-3,2) i.e. if we multiply Q(-3,2) by 3 then we get Q'(-9,6).

Similarly,
if we multiply R(-1,-5) by 3 then we get R'(-3,-15).

Does this make sense to you anisah?

Answer 12

yes

Answer 13

OK best wishes :)

Answer 14
