## Graphing Linear Equations and Slopes

Students will use Grapher software to graph linear equations and slopes.

## Objectives

- Students will explore the relationship between the slopes of perpendicular lines and parallel lines
## Procedure

- Students try to write the equations of two parallel lines and then two perpendicular lines.
- Students graph the lines using the Grapher program to check their work, they then try to adjust their equations accordingly.
- Students write a learning log entry about what changing the slope of the line will do to the appearance of the graph and about the relationship between slopes of parallel and perpendicular lines.
