Cartesian coordinate system A coordinate system consisting of intersecting straight lines called axes, in which the lines intersect at a common origin. Usually it is a 2-dimensional surface in which a "x,y" coordinate defines each point location on the surface. The "x" coordinate refers to the horizontal distance and the "y" to vertical distance. Coordinates can be either positive or negative, depending on their relative position from the origin. In a 3-dimensional space, the system can also include a "z" coordinate, representing height or depth. The relative measurement of distance, direction and area are constant throughout the surface of the system. Chips and Salsa Chips = hardware, salsa = software.
