What is the gradient?
The gradient of a line is a measure of its steepness. The gradient of the line passing through and is
In the next applet, move A and B and watch how the gradient of the line changes.
After you try different positions for A and B, answer the following questions:
Describe what needs to happen in order for the gradient to be negative.
Explain why the gradient of a horizontal line is 0.
What happens with the gradient when the line is vertical? Why do you think this happens?
