Given a natural number c ∈ N. The relation Rc is defined as follows: ∀ a, b ∈ N : (a, b) ∈ Rc ⇔ (∃ u, v ∈ Z : au + bv = c) . In other words, two natural numbers are in the relation Rc just when the number c ∈ N can be written as their integer linear combination. a) Is the relation Rc reflexive? b) Is the relation Rc symmetric? c) Is the relation Rc antisymmetric?
