George has a triangle-shaped garden in his backyard. he drew a model of this garden on a coordinate grid with vertices a(4, 2), b(2, 4), and c(6, 4). he wants to create another, similar-shaped garden, a′b′c′, by dilating triangle abc by a scale factor of 0.5. what are the coordinates of triangle a′b′c′?
