Cartesian Plane: Also known as

The cartesian coordinate plane is often seen referred to as the $x y$-plane, or (without the hyphen) the $x y$ plane.

Some sources refer to it as the Euclidean plane, but on $\mathsf{Pr} \infty \mathsf{fWiki}$ that term is reserved for the abstract geometry consisting of $\R^2$ together with the set of straight lines.
