. Define a relation on R²\{(0,0)} by letting (x₁, y₁)~(x₂,Y₂) if there exists a nonzero real number λ such that (x₁, y₁)~(2x₂, Ay₂). Prove that defines an equivalence relation on R²\{(0,0)}. What are the corresponding equivalence classes? This equivalence relation defines the projective line, denoted by P(R), which is very important in geometry.
