(a) let v = r 2 be the vector space of 2-dimensional real row vectors. decide which of the following subsets of v are vector subspaces of v and which aren’t. justify your answers. (i) l1 = {(x, y)|y = 3x}. (ii) l2 = {(x, y)|y = 3x + 1}. (iii) p = {(x, y)|y = x 2}. (b) let w = m at2×2(r) be the vector space of 2 × 2 real matrices. decide which of the following subsets of w are vector subspaces of w and which
