Slope formula:
m = (y2−y1) / (x2−x1)
Examples
- (1, 2) to (4, 8) → slope = 2
- (0, 0) to (3, 3) → slope = 1
- (2, 1) to (2, 5) → slope = undefined
FAQ
- What is slope?
Slope measures the steepness of a line and is calculated as rise over run: (y2−y1)/(x2−x1).
- What if x1 equals x2?
Then the slope is undefined because the line is vertical and division by zero would occur.
- Can slope be negative?
Yes. A negative slope means the line goes down as x increases.
- Are my coordinates stored?
No. Calculations run locally in your browser and are not stored or transmitted.
