The slope of a line measures its steepness — how much y changes for each unit increase in x. Slope is fundamental to coordinate geometry, calculus, statistics (linear regression), and everyday applications like road gradients.

Formel

Slope m = (y₂ − y₁) / (x₂ − x₁)

m: (y₂ − y₁) / (x₂ − x₁) — (y₂ − y₁) / (x₂ − x₁)

Trin-for-trin guide

1Slope m = (y₂ − y₁) / (x₂ − x₁)
2Positive slope: line rises from left to right
3Negative slope: line falls from left to right
4Zero slope: horizontal line
5Undefined slope: vertical line (x₁ = x₂)

Løste eksempler

Input

Points (0,0) and (3,6)

Resultat

Slope = 2

(6−0)/(3−0) = 2. For every 1 step right, go 2 up

Input

Points (1,5) and (4,2)

Resultat

Slope = −1

(2−5)/(4−1) = −3/3 = −1. Line falls at 45°
