SlopeIntercept Equation
In this activity you will visualize the slopeintercept equation of a line.
SlopeIntercept Formula:
y = mx + b (where m is the slope and b is the yintercept).
Activity Directions:
1) Identify the slope and the yintercept of the blue line.
2) Write the equation of this blue line.
3) Move the red slider to create new lines with different slopes.
4) Move the green slider to create new lines that have various yintercepts.
5) What type of lines have negative slopes? How do they look?
6) What type of lines have positive slopes?
7) What happens when the slope is zero?
8) What happens when the yintercept is zero?
