- Application of Linear Equations - this page is about a topic that most students hate, applications of linear equations - in other words story problems or word problems
- Fun and Sun Rent-a-Car - students use tables, graphs, linear functions to solve a real-world problem
- Graphing Linear Equations - introduction followed by an in-depth explanation, examples and two pages of practice questions
- Graphing Linear Equations: Making a T-chart (finding plot points) - four pages of instructions with several examples and illustrations
- Internet Project - let your cursor hover over the
Assessbutton and selectInternet Project- Students will collect data and then make a scatter plot and a best fit line, find the slope, y-intercept and the equation of a line [This expired link is available through the Wayback Machine Internet Archive.

- Ratio/Proportion Problems from Ask Dr. Math - three pages of links to real-world problems
- Representations of Linear Functions: Cab fares - The charge for a cab ride is determined by the length of travel. Some companies also charge a basic, fixed amount. At this site you will find descriptions of fares of three competing cab companies and you are asked to suggest a new fare.
- Slope-Intercept Form - [12 slides] this show uses animation very effectively, provides examples and the chance for student response and invludes a great real-world application of slope-intercept [This expired link is available through the Wayback Machine Internet Archive.
