Slope-Intercept Form
Use the sliders for m and b to explore this linear function then answer the questions below the graph.
This linear function has been created using the slope-intercept form. The aim of the exercise is to help you understand what the variables m and b represent and how they affect the graph of the line.
1: What happens when the value of m increases? decreases? is positive? is negative? is zero?
2: What happens when when the value of b increases? decreases? is zero?
3: Describe how the variables m and b affect the graph of the function.
