# Line choice --- Introduction ---

There are 4 ways to describe a general line (not passing through the origine, neigher vertical nor horizontal) in the cartesian plane: by an implicite equation, an equation giving $y$ as a function of $x$, one giving $x$ as a function of $y$, or a system of parametric equations.

This exercise gives you a training occasion to get familiarized with these different descriptions of the line, as well as the graphics of the line.
