Let x,y `in` Z and suppose that a relation R on Z is defined by x R y if and only if `x le y` then

Let x,y in I and suppose that a relation R on I is defined by x R y if and only if x le y . Then :

For x,y in I, the relation R is defined by xRy f and only if x<=y then R is

If R is a relation on Z defined by xRy iff x divides y then R is

If R is a relation on Z (set of all integers) defined by x R y iff |x-y|le1 , then R is

Let R be a relation in the set of natural numbers N defined by xRy if and only if x+y=18 . Is R an equivalence relation?

Let Z be the set of all integers. A relation R is defined on Z by xRy to mean x-y is divisible by 5. Show that R is an equivalence relation on Z.
