The relation R = {{a, b): both a and b are either odd or even} on the set {1, 2, 4, 5, 7, 8} is

Let R be the relation over the set A of all straight lines in a plane such that .
The R is :

Let R be a relation on the set of integers Z such that

Given relation R={(x, y) :y=x+5, x<4, x, y ϵ N}. Where N is a set of natural numbers then:

The relation R on the set N × N defined by (a, b) R (c, d) ⟺a+d=b+c ∀ (a,b) ϵ N×N is, where N is set of natural Number:

The relation R in the set A={1, 2, 3} given by R={(1, 2), (2, 1)} is:

Let R be the relation in the set {a, b, c} given by R = {a, b), (b, b), (a, a), (a, c), (c, c), (c, b)}
