Calculate slope from rise and run for ramps, grade checks, line graphs, terrain notes, and everyday geometry.
Enter job values, review the estimate, then use the decision hints before ordering or quoting.
slope = rise / runRise is the vertical change and run is the horizontal change.
The result can also be expressed as a ratio, percent grade, or angle in other tools.
Next: average rate of change.
This page is tuned for clean geometry checks during drafting or homework around line equation from two points.
When you need quick formula verification before copying a result into notes around point slope to slope intercept.
