    either show that Sp(S) = R^2 or give an algebraic specification for Sp(S). If Sp(S) =\= R^2, then give a geometric description of S.

    Sp is span, R^2 is 'two space'

    I think what the question is asking is that you have to be able to rewrite all vectors in R^2 in terms of a and c. Actually I really am not sure how to even approach this.

    the second vector is a multiple of the first (multiply by -2) so the subspace is the spaced spanned by {1,-1} in other words all multiples of this vector.

    Is [1, -1] in R^2?

    all combinations of this think will look like {x, -x} so basically you have the line \[y=-x\]
