If a figure is dilated by a scale factor of 3, what were the coordinates of the pre-image of W '(9, -3)? W(6, -6) W(12, 0) W(27, -9) W(3, -1)

OpenStudy (skarletfox):

For the first one: 2. It expanded 2 points. For the second... W(6, -3.) I believe. It expanded by 3, which meant the point moved to the right 3 times, and up 3 times.

OpenStudy (melody323):

What the answer for the second one cause that not on there

OpenStudy (skarletfox):

oh wait. I meant (6, -6) I was reading as I was typing. Sorry.

OpenStudy (melody323):

No problem. Thanks

OpenStudy (skarletfox):

No problemo
