Binary Relations

[Tesa0321]

I am having a real hard time learning my discrete math. How do you find out if a binary relation is reflexive, symmetric, antisymmetric, or transitive when you are dealing with license plates with (x,y)?

Please reply with the full and exact text of the exercise, the complete instructions, and a clear listing of everything you have tried so far (such as how you have plugged the "license plates" into the formulas for the properties you are testing).

Thank you.
