Triangle PQR with vertices P (3, - 6), Q (6, - 9), and R (-15, 3) is dilated by a scale factor of 3 to obtain triangle P′Q′R′. Which statement best describes triangle P′Q′R′?

It is similar to triangle PQR and has coordinates P′ (1, - 2), Q′ (2, - 3), and R′ (-5, 1).

It is congruent to triangle PQR and has coordinates P′ (1, - 2), Q′ (2, - 3), and R′ (-5, 1).

It is similar to triangle PQR and has coordinates P′ (9, - 18), Q′ (18, - 27), and R′ (-45, 9).
