Slope Calculator

Work out slope, gradient, distance, and the angle of a line from two points.

Slope (m)

2

Percent grade 200%
Angle 63.43°
Distance 6.7082
y-intercept (b) 1

Slope is the vertical change divided by the horizontal change. A negative slope falls left to right, and a percent grade above 100% means the climb is steeper than the ground it covers, as on a steep hill or ski slope.

What Is Slope Calculator?

The Slope Calculator works out the slope of a line from two points, then gives the percent grade, the angle from horizontal, the distance between the points, and the y-intercept. It draws the line to scale so you can check the shape.

Who Uses the Slope Calculator?

Students use it for coordinate geometry, and engineers, surveyors, and architects use it to work out road gradients and roof pitches.

How to Use the Slope Calculator

  1. Enter the x and y values for both points.
  2. Read the slope, percent grade, and angle.
  3. Copy the line in either slope-intercept or point-slope form.

Why Choose Our Slope Calculator?

  • Slope, gradient, angle, and distance together
  • Handles negative slopes from falling lines
  • Drawn to scale with the result labelled
