points (1,2) and (2, 1/2) are moved to (4,3) and (3 1/2, 1) write the mapping rule ( plz help if you can, and dont send a link)

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
