Test the set of matrices for linear independence in m22. if it is linearly dependent, express one of the matrices as a linear combination of the others. (if the set is linearly independent, enter independent. if the set is linearly dependent, enter your answer as an equation using the variables a, b, and c as they relate to the question.) a = 1 1 0 −1 , b = 1 −1 1 0 , c = 1 0 7 6
