It has recently been shown that hadrons containing a single heavy quark exhibit a new flavor-spin symmetry of QCD. We exploit this symmetry to obtain model independent predictions for the form factors for the semileptonic decay of the Lambda(sub)b to the low-lying negative parity charm baryons. We discuss the connection between these results and the slope of the universal function Zeta that determines the Lambda(sub)b->Lambda(sub)c weak form factors.
