Answer 8

So, look at your coordinates. The pre-image has (2,3), (0,0), and (-2,1) right? And your image is (6,9),(0,0), and (-6, 3). What happened from the pre-image to the image? Did it grow bigger, or did it get smaller?

Answer 9

It got bigger?

Answer 10

Yeah, exactly. The pre-image expanded into the bigger image cause the coordinates grew larger as well. Meaning that it was....?

Answer 11

Expansion?

Answer 12

yeah. or atleast i believe so. ;)
