Triangle PQR is dilated by a scale factor of 1.5 to form triangle P′Q′R′. This triangle is then dilated by a scale factor of 2 to form triangle P″Q″R″. If vertex P is at (3, - 4) and vertex Q is at (5, - 1), what are the coordinates of vertices P″ and Q″?

P″ (4.5, - 6) and Q″ (7.5, 1.5)

P″ (4.5, - 6) and Q″ (7.5, - 1.5)

P″ (-9, 12) and Q″ (15, - 3)

P″ (9, - 12) and Q″ (15, - 3)

P" (-9, - 12) and Q" (-15, - 3)

    P″ (4.5, - 6) and Q″ (7.5, - 1.5) all you do is multiply each number by 1.5
