Find the slope between two points, plus the y-intercept and the full slope-intercept equation of the line.
How it works
- Enter the X and Y coordinates for your first point.
- Enter the X and Y coordinates for your second point.
- The calculator derives the slope (m) and the y-intercept equation.
Frequently asked questions
What does slope mean?
The steepness and direction of a line: positive rises left to right, negative falls, zero is flat.
Why is a vertical line undefined?
It has no horizontal change (run = 0), and dividing by zero is undefined.
What is slope-intercept form?
y = mx + b, where m is the slope and b is where the line crosses the y-axis.
