So many methods and so little time! The efficient method of graphing a linear equation depends on what information the problem gives. Pupils learn three different methods of graphing linear equations. They graph equations using input/output tables, using slope and y-intercepts, and by finding the x and y-intercepts. The resource also challenges pupils to graph a parabola for comparison.

Instructional Ideas

• Use the provided examples to help your classes determine the best graphing method in a given situation
• Have your pupils use a graphic organizer to record linear equations in different forms and the different methods of graphing

Classroom Considerations

• Builds on previous lessons in the series
• Assumes a familiarity with linear equations, slope, and intercepts

Pros

• Shows various graphing methods, which encourages learners to think through a problem first

Cons

• The inclusion of quadratic equations when the focus has been on linear equations seems random
