Slope-Intercept Slider Tool
- Ben Dougherty
Use the slider bars to change the slope (m) and y-intercept (b) of the line. Explore what happens when both are negative, positive, and zero.
1) How is the line different as it's slope (m) changes from positive to negative? 2) What is the difference between a slope (m) of less than 1 versus a slope (m) of greater than 1? 3) As the slope increases, what happens to the line? Is the line ever completely vertical? 4) Set the slope to zero and the y-intercept (b) to a value other than zero. What kind of line has a slope of zero? 5) How does changing the y-intercept (b) affect the line?
