Determine if the statement is true or false, and justify your answer. If {u1, u2, u3} is a basis for R3, then span{u1, u2} is a plane. True. The vectors {u1, u2} are linearly dependent, and hence span a two-dimensional subspace, a plane. True. The vectors {u1, u2} are linearly independent, and hence span a two-dimensional subspace, a plane. False. The vectors {u1, u2} are linearly independent, and hence span a one-dimensional subspace, a line. False. The vectors {u1, u2} are linearly dependent, and hence span a one-dimensional subspace, a line. False. The vectors {u1, u2} are linearly indepe
