Step-by-step Answer:
A dilation about (0,0) or origin has the rule
(x,y) -> (kx,ky)
where k is the scale factor, (x,y) denotes the preimage, and (kx,ky) denotes the image.
For B(-8,-2), and k=12,
we have
B'(-8*12,-2*12) = B'(-96,-24)
Answer:
(-8,-2)

Perry’s ratio of Swiss chess to cheddar cheese is 5:7.
Wrong ratio because 5 * 3 = 15 but 7 * 3 does not equal 17.
