Parameters can move and change the steepness of a graph. Introduce the effects of changing the slope or the y-intercept of a linear graph. The resource shows how to incorporate changes on graphs and how they will move up, move down, become steeper, or become flatter.

Concepts

linear functions, graphing linear equations, linear equations, slope, slope-intercept form, y-intercepts, parameters

Instructional Ideas

• Use the video to help pupils that are having a difficult time understanding the concept or were absent the day of instruction 
• Have class members create situations with graphs and ask for the parameter change that can cause a desired effect

Classroom Considerations

• The class members should be familiar with graphing linear equations

• This video is hosted on YouTube

Pros

• Contains three examples on the effects of parameter changes on the graph
• Beginning of the resource explains in general what parameters can be changed in a linear function

Cons

• None
