How to Use This Calculator
- Enter the X and Y coordinates for Point 1 (X1, Y1)
- Enter the X and Y coordinates for Point 2 (X2, Y2)
- Click the "Calculate" button to compute the incline rate
- The calculator will display the slope, rise, run, and angle in degrees
Understanding the Results
The incline rate (or slope) measures how steep a line is. It's calculated as the ratio of the vertical change (rise) to the horizontal change (run) between two points:
Slope = (Y2 - Y1) / (X2 - X1)
Practical Applications
- Architecture and construction for roof pitch and stair design
- Geography for measuring terrain elevation changes
- Navigation for plotting courses between points
- Engineering for determining gradient of roads and pathways
Special Cases
The calculator handles special cases:
- Horizontal line: When X2 = X1, the slope is 0 (flat)
- Vertical line: When Y2 = Y1, the slope is infinite (90° angle)
