It is given that Relation R in the set A = {1, 2, 3, ..., 13, 14} defined as

R = {(x, y) : 3x – y = 0}

Then, R = {(1,3), (2,6), (3,9), (4,12)}

R is not reflexive as (1,2), (2,2) …… (14,14) ∉ R

Also, R is not symmetric as (1,3) ϵ R, but (3,1) ∉ R

And, also R is not transitive as (1,3), (3,9) ϵ R, but (1,9) ∉ R

Therefore, R is neither reflexive, nor symmetric, nor transitive.
