In this activity, you will be observing what happens to the graph of a linear equation when the slope and/or y-intercept increase or decrease.

1) As you move the slider for the slope, m, to the right, what happens to the graph? What happens as you move it to the left?
2) As you move the slider for the y-intercept, b, to the right, what happens to the graph? What happens as you move it to the left?
3) Based on this activity, what does the slope tell you about the graph of a line?
4) Based on this activity, what does the y-intercept tell you about a the graph of a line?
