This is for student to investigate the gradient of an interval and for them to develop a general gradient formula.
m is the gradient of the interval AB. Use the sliders on the right to change the coordinates of A and B and see what it does to the gradient.
1)What happens to m when the interval is horizontal?
2)What happens to m when the interval is vertical?
3)What happens to the interval when m=0?
4)What happens to the interval when m>0?
5)What happens to the interval when m<0?
6)How is m calculated?
7)Come up with a general rule to find the gradient between any 2 points.
