Working
- 1m = (12 − 3) ÷ (8 − 2) = 1.5
Quick answer
Slope is rise over run: m = (y₂ − y₁) ÷ (x₂ − x₁).
m = (y₂ − y₁) ÷ (x₂ − x₁)

Frequently asked questions
What is a negative slope?
The line falls left to right — y decreases as x increases.
What does percent grade mean?
Slope expressed as a percentage, used for roads and ramps. A 5% grade rises 5 feet over 100 feet of run.
