Interpret the Rate of Change/Slope and Intercepts within the Context of Everyday Life

Curated and Reviewed by Lesson Planet

Rates of change can be a slippery slope. The resource makes the connection between the rate of change and the slope of a line. It continues on to provide examples of how to interpret the slope and the y-intercepts of linear equations that represent everyday contexts. The examples are converted into equations to highlight the slope and the intercept.

Instructional Ideas

Have class members come up with ideas that have a constant rate of change and provide an interpretation of its intercepts

Classroom Considerations

The aligned standard is not the best standard for this concept; a better match would be 8.F.B.4
The class should be familiar with calculating slopes of linear realtionships

Pros

Examples use different representations of the functions; verbal, tabular, and graphical
Reviews the slope-intercept form of linear equations

Cons

The last example is completely different than the previous examples
