4. Define the relation, R, on the set (1,2,3,4.5} so that (x, y) ER if 3 dividesx + y. NOTE: b divides a if there exists an integer k so that a = k . b. So for example, 2 divides 6 because of the existence of the integer 3 such that 6=3 -2. So in this case, "divides" really means "divides evenly." a. List the elements of R. b. Explain why R is or is not reflexive, symmetric, and transitive. You must provide justification
