Line g is dilated by a scale factor of one half from the origin to create line g'. where are points e' and f' located after dilation, and how are lines g and g' related?

the locations of e' and f' are e' (−8, 0) and f' (0, 4), and lines g and g' intersect at point f.
the locations of e' and f' are e' (−4, 0) and f' (0, 2), and lines g and g' are the same line.
the locations of e' and f' are e' (−2, 0) and f' (0, 1), and lines g and g' are parallel.
the locations of e' and f' are e' (−1, 0) and f' (0, 0), and lines g and g' are not related.
