Answer:
A' = (- 6, - 6 ) , B' = (- 12, - 9 ) , C' = (- 6, - 15 )
Explanation:
since the dilatation is centred at the origin, multiply each of the original coordinates by the scale factor of 3
A' = (3(- 2), 3(- 2) ) → A' (- 6, - 6 )
B' = (3(- 4), 3(- 3) ) → B' (- 12, - 9 )
C' = (3(- 2), 3(- 5) ) → C' (- 6, - 15 )
