Question

CARD #2:

A figure on a
coordinate plane is
dilated. Point A(3, 9)
is dilated to A'(1, 3).
Bobby says the
dilation can be
represented by
(x, y).
Betty says the
dilation can be
represented by
(3x, 3y).

Answer 1

(3x,3y) if you're representing the dilation from A' -> A

Explanation:

I think that it would be (3x, 3y) bc the original point was dilated by 1/3 (3 x 1/3 = 1, 9 x 1/3= 3), so I'm wondering which dilation it specifies for exactly, b/c if its for A', then the answer would be Betty. Hope this helps somewhat tho
