This system is composed of two number lines that are perpendicular at their zero points. This scheme is called the Cartesian coordinate system (for Descartes) and is sometimes referred to as the rectangular coordinate system. Rene Descartes (1596-1650) devised a method of relating points on a plane to algebraic numbers. Note that this concept contains elements from two fields of mathematics, the line from geometry and the numbers from algebra. We have already used the number line on which we have represented numbers as points on a line. Given a point on the Cartesian coordinate system, state the ordered pair associated with it.Given an ordered pair, locate that point on the Cartesian coordinate system.Represent the Cartesian coordinate system and identify the origin and axes.Upon completing this section you should be able to: We will now study methods of solving systems of equations consisting of two equations and two variables. In previous chapters we solved equations with one unknown or variable.
