Question:
△MNO has vertices M(8,−2), N(−15,−20) and O(−14,19). Which of the following represents the translation of △MNO along vector <7,−2> and its reflection across the y-axis?

M (8, −2) → M ′(1, 0) → M ″(1, 0);
N (−15, −20) → N ′(−22, −18) → N ″(−22, 18);
O (−14, 19) → O ′(−21, 21) → O ″(−21, 21)

M (8, −2) → M ′(1, 0) → M ″(−1, 0);
N (−15, −20) → N ′(−22, −18) → N ″(22, −18);
O (−14, 19) → O ′(−21, 21) → O ″(21, −21)

M (8, −2) → M ′(15, −4) → M ″(−15, −4);
N (−15, −20) → N ′(−8, −22) → N ″(8, −22);
O (−14, 19) → O ′(−7, 17) → O ″(7, 17)

M (8, −2) → M ′(1, 0) → M ″(1, 0);
N (−15, −20) → N ′(−8, −22) → N ″(−8, 22);
O (−14, 19) → O ′(−7, 17) → O ″(−7, −17)
