Explanation:
#"let the images of A,B" and "C be"#
#A',B'" and "C'" respectively"#
#"since the dilatation is centred at the origin then the"#
#"coordinates of the images are just twice the coordinates"#
#"of the original points"#
#"ONLY for dilatations centred at the origin"#
#rArrA'=(-12,-14),B'=(8,-4),C'=(0,14)#
