How this calculator works
Compute slope from two points with rise and run breakdown.
Formula
slope (m) = (y2 - y1) / (x2 - x1)
Step-by-step
- Enter x1 and y1 for point 1.
- Enter x2 and y2 for point 2.
- Calculate to get slope, rise, and run.
Example
- (x1, y1) = (2, 3)
- (x2, y2) = (8, 15)
m = (15 - 3) / (8 - 2) = 2
FAQs
What if x2 equals x1?
Slope is undefined because the line is vertical and run equals zero.
Can slope be negative?
Yes. A downward line from left to right has a negative slope.
