    It cannot be reflexive, because (1,2) (2,1) It is symmetric I think.

    You sure it's reflexive? Because reflexive is only when f(x) such that (a,a) belongs to R where R is the set of all real numbers and (1,2) and (2,1) are not reflexive.

    its considered when reflexive when (a,a) is an element of R

    thus (1,1) and (2,2) and (3,3) (4,4)

    plat the points... draw the line y=x and then if the points are equidistant from the line and when joined... the interval is perpendicular to y = x the point is reflected in y = x
