Let R be the relation on the set R real numbers defined by xRy iff x−y is an integer. Prove that R is an equivalence relation on R. Proof. I. Reflexive: Suppose x ∈ R. Then x−x = 0, which is an integer. Thus, xRx. II. Symmetric: Suppose x,y ∈ R and xRy. Then x − y is an integer. Since y −x = −(x−y), y −x is ...
