How to calculate slope
This calculator finds the slope of a line between two points — a fundamental concept in algebra and coordinate geometry.
How the calculation works
Slope = (y₂ − y₁) ÷ (x₂ − x₁).
Example
Points (2, 3) and (6, 11): (11−3)÷(6−2) = 8÷4 = 2.
Frequently asked questions
How is Result calculated?
Result = ([yu2082] − [yu2081]) ÷ ([xu2082] − [xu2081]).
Is the Slope Calculator free to use?
Yes — every calculator on Simple Calculator Tools is free, runs in your browser, and does not require an account.

Pro Tips for Slope
- A positive slope means the line rises left to right; negative means it falls; zero slope means a horizontal line.
- A vertical line has an undefined slope, since the denominator (x₂−x₁) would be zero — this is a special case this formula can't handle directly.
Common Slope Mistakes to Avoid
- Mixing up the order of subtraction between the two points (like computing y₁-y₂ in the numerator but x₂-x₁ in the denominator), which flips the sign of the result.
