CCSS.Math.Content.8.F.B.4 - Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.

1. Graphing Linear Equations: Making a T-chart (finding plot points) - Four pages of instructions with several examples and illustrations
2. Graphing Non-Linear Functions - Two examples with explanations of each
3. Linear Equations - Lesson plan for two or three class periods, the document includes links to worksheets
4. Nonlinear Functions and their Graphs - A 14 slide show [you might want to delete the two assignment slides, they probably don't match your textbook]
5. Positive Linear Function Machine - This activity allows the user to explore simple linear functions; the function is determined by looking for patterns in the outputs.
6. Rate of Change Practice Problems - Nine practice problems (including a graph to interpret) followed by an answer key
7. Rate of Change: Connecting Slope to Real Life - A lesson on using slope to find the rate of change accompanied by graphs and explanations
