Answer:

Explanation:

A ( 2 , 6 ) ------> A' ( 0 , 2 )

B ( 5 , 3 ) ------> B' ( 1 , 1 )

Equation of the line AA' is y = 2x + 2

Equation of the line BB' is y = ( 1 / 2 ) x + 1 / 2

AA' ∩ BB' = ( - 1 , 0 ) <----- this point is a center of the dilation with the scale 1 / 3

D ( - 4 , - 3 ) -------> D' ( - 2 , - 1 )

C ( 2 , - 3 ) -------> C' ( 0 , - 1 )
