For points (x, y) and (u, v) in the set R?, define (x, y) ~ (u, v) if and only if r – y = u – v. (a) Prove that ~ defines an equivalence relation on R². (b) Compute the equivalence class of the point (0, 4). The collection of points in this class deter mines a common geometric object in R2. Describe it.
