Final answer:
After dilating line f by a scale factor of 2 with the center of dilation at the origin, points A' and B' are located at (0,4) and (4,0) respectively. Lines f and f' are parallel.
Step-by-step explanation:
When a line is dilated by a scale factor of 2 with the center of dilation at the origin, each point on the original line is multiplied by 2 to determine the corresponding point on the dilated line.
In this case, for point A(0,2), the x-coordinate remains the same and the y-coordinate is multiplied by 2 to give point A'(0,4). Similarly, for point B(2,0), the y-coordinate remains the same and the x-coordinate is multiplied by 2 to give point B'(4,0).
Since the corresponding points on the dilated line f' are collinear and each point is multiplied by the same scale factor of 2, lines f and f' are parallel.
