Question

A dilation has center (0, 0, 0). Find the iamge of the point (-1, -2, 0) for the scale factor of 3. Please help!

Answer 1

I know what a dilation is, it's basically just the image reduced or enlarged, but i don't know what the question is asking.

Answer 2

@phi any help?

Answer 3

I think the "image point" is where the "start point" ends up after you apply the dilation
In your case, multiply each component by 3

Answer 4

So the new image point would be (-3, -6, 0)?

Answer 5

yes

Answer 6

Ok, thanks! :) also, can i ask a couple more questions?

Answer 7

The endpoints of line segment AB are A(9, 4) and B(5,-4). The endpoints of its image after dilation are A'(6, 3) and B'(3, -3). Explain how to find the scale factor. So based on how you said before, the scale factor is what we multiply each point by, so what i would do here is AB/A'B'?
