Select the correct answer. Vector u has its initial point at (1, -12) and its terminal point at (18,6). Vector v points in a direction opposite that of u, and its magnitude is three times the magnitude of u. What is the component form of vector V? OA. v=(-51, -54) O B. v=(-51, 18) Ocv=(51, -54) OD. v = (51, -18)
