Slope Calculator

Summary

Enter two coordinate points and instantly get slope, angle, y-intercept, and the line equation in slope-intercept form.

How it works

1. Enter the x and y coordinates for your first point (x1, y1).
2. Enter the x and y coordinates for your second point (x2, y2).
3. Click "Calculate" or press Enter — results appear instantly.
4. Slope is shown as a simplified fraction (rise/run) and a decimal.
5. Angle with the x-axis is computed via arctangent of the slope.
6. The y-intercept and full slope-intercept equation are displayed.
