    Question in attachment is as follows:
    Consider all lines in the plane. If a relationship between 2 lines is defined by the expression that their slopes are equal, prove that this relationship is an equivalence relationship.

    If we consider the set of all lines in the plane, how would you uniquely identify the equivalence classes?

    Solution Preview

    In order to prove that a relationship is an equivalence relationship, one must show reflexivity, symmetry and transitivity.
    Let x, y and z be lines in the plane

    reflex: x R ...

    Solution Summary

    This shows how to uniquely identify the equivalence classes. The set of all lines in the planes are calculated.
