Show that the vectors (x1, y1) and (x2, y2) are linearly dependent—that is, not linearly independent—if any of the following conditions are satisfied.
(a) If
(b) If for some constant λ.
(c) If x1 y2 − x2 y1 = 0. Hint: Assume x1 is not zero; then But , and we can use part b. The other cases are similar. Note that the quantity is the determinant of the matrix
