F3. Gradient and intercept : gradient
| A straight line is plotted on a graph and two points A
and B are chosen anywhere on the line. |
 |
A right-angled triangle can be formed under this line
and the "rise" and "step" can be found.
The gradient, or slope, of the
line can be measured by calculating:
gradient=rise / step |
|
 |
Use your mouse to move points A and B. The
rise and step of the line passing through A and B is displayed, together with
the gradient of this line. How does the gradient vary as A and B vary?
