Slope Calculator
Enter two coordinate points to calculate the slope and full equation of the line through them.
slope = 3
y = 3x − 1
How to use this tool
- 1Enter the coordinates of two points.
- 2See the slope and line equation (y = mx + b).
Frequently asked questions
What if both points have the same x-coordinate?+
That's a vertical line, which has an undefined slope — the tool flags this case instead of showing a number.
