Formula and methodology
Formula: Average rate of change=(y2−y1)/(x2−x1), with x2≠x1.
The y change and x change are shown before their ratio, making the interval direction visible.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- First x — minimum -1000000000; maximum 1000000000
- First y — minimum -1000000000; maximum 1000000000
- Second x — minimum -1000000000; maximum 1000000000
- Second y — minimum -1000000000; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| First x | 2 |
| First y | 5 |
| Second x | 8 |
| Second y | 17 |
Average rate of change =2.
Assumptions and limits
- The two x coordinates are distinct and all inputs are finite.
- The result is a secant slope over the selected interval.
- Instantaneous derivatives, nonlinear fit, measurement uncertainty, and extrapolation are not modeled.
