Notes for Week 7 Name: ______________________________ MAT 0024C Chapter 4: Graphing Linear Equations and Inequalities 4.1 The Rectangular Coordinate System  The Rectangular Coordinate System  A rectangular coordinate system is formed by two perpendicular number lines. The horizontal number line is usually called the x-axis and the vertical number line is usually called the y-axis.  The point where the axes intersect is called the origin.  The axes form a coordinate plane, and they divide it into four regions called quadrants, which are numbered using Roman numerals as shown below:  Each point in a coordinate plane can be identified by an ordered pair of real numbers x and y written in the form (x,y). The first number x in the pair is called the x-coordinate, and the second number y is called the y- coordinate.  The process of locating a point in the coordinate plane is called graphing or plotting the point. 1 Examples: Q: Plot each point and state the quadrant i...
