Instructional Ideas

• Use as a review for writing linear equations given various pieces of information
• Assign pupils several problems given various pieces of information mixed together; have them write the equation in just point-slope form

Classroom Considerations

• Pupils should already have an understanding of writing equations of lines, as the lesson is designed as a review
• Requires Internet access to watch a YouTube video
• A continuation of a 29-part series about functions

• This video is hosted on YouTube

Pros

• The instructor breaks down the ways the information can be presented into three categories, allowing learners to see the relationships between all types
• Simplifies all problems to slope-intercept form

Cons

• None
