In the triangle LJK, the length of side LK=18.

In the triangle L'J'K', the length of side L'K'=6

Therefore,


L^(\prime)K^(\prime)=(1)/(3)LK=(1)/(3)*18=6

Therefore, the scale factor for dilation is 1/3.

So, the dilation can be represented as


(1)/(3)X,(1)/(3)Y

So, Emily's statement is correct.
