Let A = R x R, and let a relation S be defined as: “(x1 , y1 ) S (x2 , y2 ) ⬄ points (x1 , y1 ) and (x2 , y2 ) are 5 units apart.” Determine whether S is reflexive, symmetric, or transitive. If the answer is “yes,” give a justification (full proof is not needed); if the answer is “no” you must give a counterexample
