Graphing Equations on the Cartesian Plane: Slope

Curated and Reviewed by Lesson Planet

Slopes are not just for skiing. Instructors introduce class members to the concept of slope and teach them how to calculate the slope from a graph or from points. The lesson also includes the discussion of slopes of parallel and perpendicular lines.

Instructional Ideas
  • Provide the class several opportunities for guided practice
  • If this is the first exposure to slope for the class, consider delaying the discussion of parallel and perpendicular lines until they can calculate slope proficiently 
Classroom Considerations
  • The class should be able to graph points on the coordinate plane in all four quadrants
  • The fourth part in a nine-part series
Pros
  • The homework has an answer key
  • The closure has the pupils consider how the concept will aid in the challenge for the unit
Cons
  • The graphs on the homework are screen captures of calculator graphs and may be difficult to read
