ANSWER:
Given a dilation with origin O(0, 0).
Given the coordinates:
K(x1, y1) ==> (x2, y2) = (6 , 12) ==> (3, 6)
To find the dilation of the scale factor that occured here, divide the new coordinates by the old coordinates.
We have:
From the calculations above, we can see a dilation with a scale factor of 1/2 occured.
ANSWER:
1/2
