This exercise is an opportunity for algebra learners to understand the connection between the slope of a line and points found on the line. Use similar triangles to explain why slope m is the same between any two points. Discuss with the class the concept that if the y intercept changes, there is a proportional relationship between the line graphs.
- An good introduction of point-slope form of an equation
- The effect of the y intercept, b, is not clear
- May need to break down into smaller parts
