ANSWER:


(1)/(2)

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:


\begin{gathered} (y1)/(x1)=\text{ }(3)/(6)\text{ = }(1)/(2) \\ \\ (x2)/(y2)=(6)/(12)=(1)/(2) \end{gathered}

From the calculations above, we can see a dilation with a scale factor of 1/2 occured.

ANSWER:

1/2
