The primary focus in this activity is on parallel lines and equivalent equations. In Activity 1 and Activity 2, the class collectively will create a system of parallel and coinciding lines. It is important to focus on parallel lines having the same slope, but different y-intercepts; and coinciding lines having the same slope and y- intercept. There is also an opportunity to discuss solutions to systems of equations; you can focus on the solution to the system of equations using both the motion and the
