A has the coordinates (–4, 3) and B has the coordinates (4, 4). If DO,1/2(x, y) is a dilation of △ABC, what is true about the image △A'B'C'? Check all that apply.AB is parallel to A'B'.DO,1/2(x, y) = The distance from A' to the origin is half the distance from A to the origin.The vertices of the image are farther from the origin than those of the pre-image.A'B' is greater than AB.
