PLEASE RATE! :) This is a "Round Table" Activity.
Students will sit in groups of four and each will be given a separate graph with four questions. Each will find the slope according to their graph in question 1. They will then rotate their papers one person and write the equation of the requested line in slope intercept form. Another rotation will have each student write the equation of a parallel line to the requested line in standard form. One more rotation will have students write the equation of a particular perpendicular line in point slope form.
After all equations have been written, students should rotate once more and they will have the graph they originally began with. Each student should now check their group members' work to make sure they correctly wrote the equations of the lines.
