A Cartesian coordinate system in a plane is a coordinate system that uniquely describes each point by a pair of numerical coordinates that are the signed distances to the point from two fixed perpendicular oriented lines measured in the same unit of length.
A coordinate plane is a two-dimensional number line in which the vertical line is referred to as the [tex]y\,-[/tex] axis and the horizontal line is referred to as the [tex]x\,-[/tex] axis.
A horizontal line passing through the origin that includes both positive and negative numbers is called [tex]\boldsymbol{x\,-}[/tex] axis
