Question

Given a dilation around the origin, what is the scale factor K?
DO, K = (9,6) → (3,2)

1/3
4
3/2
3

Answer 1

Answer:

  (a)  1/3

Step-by-step explanation:

When dilation is centered on the origin, the ratio of the coordinate values is the dilation scale factor:

  k = x'/x = 3/9 = y'/y = 2/6

  k = 1/3
