Details Consider the vectors u = <- - 1,9 > v = < - 7, - 2, 6 >, and 2 73 28 w = k>. What value of k will cause the set {u, v, w} to be linearly dependent? You may 7 7 5 5 submit your answer as a fraction, if necessary. (The use of a computer algebra system may be used to reduce any matrices involved.) k = makes the set linearly dependent
