Define a relation Q on the set R × R as follows. For all ordered pairs (w, x) and (y, z) in R x R, (w, x) Q (y, z) = x = z. (a) Prove that Q is an equivalence relation. To prove that Q is an equivalence relation, it is necessary to show that Q is reflexive, symmetric, and transitive. Proof that Q is an equivalence relation:
