Elementary Algebra (Ch.3) Graphing Lines

Elementary Algebra is an open textbook that is available to read for free on the flatworld knowledge website. Chapter 3 is an introduction to graphing linear equations. In this chapter, we learn how to graph lines in the rectangular coordinate plane and make connections between linear equations and lines. In addition, functions are introduced and linear inequalities are solved where the solutions are represented graphically and using interval notation.


3.1 Rectangular Coordinate System
3.2 Graph by Plotting Points
3.3 Graph using Intercepts
3.4 Graph using the y-intercept and Slope 

3.5 Finding Linear Equations
3.6 Parallel and Perpendicular Lines
3.7 Introduction to Functions
  
3.8 Linear Inequalities (Two Variables) 

In addition, you will find a complete review exercise section and a practice test.

3.9 Review Exercises and Sample Exam
