This activity helps students connect several algebraic relationships: slope, y-intercept, multiple representations, linear equations, slope-intercept form, functions, proportionality and systems of equations. From a real world scenario, students build a table and a graph. They then find the slope and y intercept to create the slope-intercept equation. They determine if the relationship is a function and if it's proportional or non proportional. Once they complete two full equations, they find the solution to the systems.
