I'll split the question up into subsets. You can then agglutinate the solutions and deliver the result to your professor.
a) Give explicitly the set of elements related to (0, 0)
b) Draw (0, 0)'s equivalence class
c) Repeat a) and b) for a random element of the plane.
d) Find and draw a subset of the plane which contains exactly one representative of each equivalence class.
