Theory of Sets, chapter II, § 6. Equivalence relations

The relation " $x \in E$ and $y \in E$ " is an equivalence relation on E, whose graph is $E \times E$ .

Bourbaki sets the proof directly after the statement, and the corpus does not separate them, so what is above is the statement and its proof together.
