CHAPTER 12LINEAR EQUATIONSIN TWO VARIABLESThus far in this course, discussions of equations have been limited to linear equations inone variable. Linear equations which have twovariables are common, and their solution involves extending some of the procedures whichhave already been introduced.RECTANGULAR COORDINATESAn outstanding characteristic of equations intwo variables is their adaptability to graphicalanalysis. The rectangular coordinate system,which was introduced in chapter 3 of this course,is used in analyzing equations graphically. Thissystem of vertical and horizontal lines, meetingeach other at right angles and thus forming arectangular grid, is often called the Cartesiancoordinate system. It is named after the Frenchphilosopher and mathematician, Rene Descartes,who invented it.COORDINATE AXESTherectangularcoordinate system is developed on a framework of reference similar tofigure 3-2 in chapter 3 of this course. On apiece of graph paper, two lines are drawn intersecting each other at right angles, as infigure 12-1. The vertical line is usually labeledwith the capital letter Y and called the Y axis.The horizontal line is usually labeled with thecapital letter X and called the X axis. Thepoint where the X and Y axes intersect is calledthe ORIGIN and is labeled with the letter o.Above the origin, numbers measured alongor parallel to the Y axis are positive; below theorigin they are negative. To the right o
