Please help its my birthday :) What is the equation of the function?

Question 17 options:

y=(2/3)x

y=2(3)x

y=3(2/3)x

y=2(3/2)x

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.
