Question

Which is the image of Point A under a dilation centered at the origin described by the rule (x,y)-(4x-4y) ?

Answer 1

Ahh I forgot how to do this I used to do these a lot. If you could ask someone else? then they could help i'm sorry. Math is not my best subject.

Answer 2

hmm. Any background info, or answer choices?

Answer 3

I'm going to assume there should be an image?

Answer 4

A:(8,4) B:(1/2,1/4) C:(-1/2,-1/4) D:(-8,-4)

Answer 5

Or at least a coordinate for "Point A"

Answer 6

Okay perfect...if A = (-2,-1)


The translation (x , y) -> (4x , 4y) just means you take the original values of (x and y) and multiply them by '4'

So

(x , y) = (-2 , -1) --> (-2(4), -1(4)) = (? , ?)

Answer 7

(-8,-4) @johnweldon1993

Answer 8

Correct!

Answer 9

Which is the image of Point B under a dilation centered at the origin with scale factor 1/3 ?

A:(1/3,-2/3) B:(3,-6) C:(4/3,-5/3) D:(-3,6)
