For each of the following relations on the set of real numbers, determine if it satisfies each the following conditions (enter $Y$ or $N$ in each of the boxes):

	Reflexive	Symmetric	Transitive	Equivalence Relation
$x \sim y \Leftrightarrow x^2 > y^2$
$x \sim y \Leftrightarrow x \leq y$
$x \sim y \Leftrightarrow x^2+y^2=2$
$x \sim y \Leftrightarrow |x-y|<6$
$x \sim y \Leftrightarrow xy=0$
