    Parallel vectors.

    I'm stuck with this question. I'm clueless as of this point.

    Given A = 5i + j and B = 2i + kj where k is a scalar find k such that A and B are parallel.

    2 vectors are parallel when they have the same direction.

    This means A = cB (where c is a scalar).
    Now can you setup the equations to solve for k?

    Solve \dfrac{2}{5}=\dfrac{k}{1}
