    Vector

    On the Cartesian plane, if vector WV extendeds from the origin to (2,1) how do you make vector WV = 0, cordinates are in the (I,J) format.

    I have no idea what you mean by "make vector WV= 0". You are telling us that WV= 2\vec{i}+ \vec{j} and that is NOT 0.

    If the question were, which of the above vectors do you add to WV to get the zere vector 0 then the answer is c.
    Note the 'red' correction.

    If you are asked to find a vector such that the product of WV and this vector equals zero then the answer is b)
