Slope Calculator
Calculate the slope of the line through two coordinate points.
Inputs and results stay in this browser. Change one value at a time to explore the relationship.
Calculation steps
- Rise = 10 − 2 = 8.
- Run = 5 − 1 = 4.
- Slope = 8 ÷ 4 = 2.
Definition and formula
Slope is vertical change divided by horizontal change. Positive slopes rise from left to right; negative slopes fall.
m = (y₂ − y₁) ÷ (x₂ − x₁)
Worked example
For (1, 2) and (5, 10), m = (10 − 2) ÷ (5 − 1) = 2.
Common mistake
Subtract coordinates in the same order in both the numerator and denominator.
How to learn with this calculator
Begin with the worked example, then change one value while keeping the others fixed. Compare the new result and calculation steps to identify which part of the formula changed.
