true, the dot products of a₁ and a₂ with y is non-negative, while the dot product of b with y is negative. Geometrically, this means that a₁ and a₂ stays on the same half-plane as y (blue in below graph), while b stays on the opposite half-plane (orange): Geometric interpretation of Farkas lemma We
