Exploring Slope and the Y-Intercept
Move the sliders, m and b and watch how the slope and Y-Intercept change. Notice the equation changes as you change the slope and intercept.
You can 'grab' a point and move it.
Use the slider below to change the value of m. How does this change the graph?
Use the slider below to change the value of b. How does this change the graph?
To be sure you understand the slope, move the points and use the slope formula to see if you can come up with the same slope!
