This activity is intended to be a discovery activity for students to determine the effect that changing m and b have on the equation y=mx+b. There is a teacher guide and an activity to determine the student's level of understanding.

Before beginning the activity the teacher does not need to define slope or y-intercept. The activity is designed as an introduction to these concepts and when completed will help students to have the big picture of slope and y-intercept and how changing the variables in the slope intercept equation will affect the graph.

All directions are included in the above attachment.

The final page of the activity provides a worksheet for students. This page will allow the teacher to determine the students' understanding of the concepts.
