x,y) ---------> (2/3x, 2/3y)
1) For that dilation, we always start from the pre-image. In this case, the ABC is the bigger one
So taking one point of that triangle as an example.
C(9,3)
And one of that image
C'( 6,2)
Dilating from C to C' all other points follow that same rule.
2) This leads us to conclude
Pre image Image
(x,y) ---------> (2/3x, 2/3y)
