    you are given initial and terminal point of a vector, so you need to find that vector (not a sum)

    52.

    let points be A and B , and vector AB
    [​IMG]


    A=(0,-2) and B=(3,6)
    AB = {Bx - Ax; By - Ay} = {3 - 0; 6- (-2)} = {3; 8}
    Answer: AB = {3; 8}
    in standard form AB =<3i; 8j>

    same way you do all problems above
