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.
- Have class members come up with ideas that have a constant rate of change and provide an interpretation of its intercepts
- 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
- Examples use different representations of the functions; verbal, tabular, and graphical
- Reviews the slope-intercept form of linear equations
- The last example is completely different than the previous examples
