How to Calculate Slope
Formula
m = (y₂ - y₁) / (x₂ - x₁)
The slope represents the rate of change — how much y changes for each unit increase in x.
Line Equation
Once you have the slope (m) and y-intercept (b), the line equation is: y = mx + b
Where b = y₁ - m × x₁
Exemple Résolu
Find the slope of the line through points (1, 2) and (4, 8).
- 01Slope = (8 - 2) / (4 - 1) = 6 / 3 = 2
- 02Y-intercept: b = 2 - 2 × 1 = 0
- 03Line equation: y = 2x
- 04Distance = √((4-1)² + (8-2)²) = √(9 + 36) = √45 ≈ 6.7082
Questions Fréquentes
What is slope?
Slope measures the steepness and direction of a line. It is the ratio of the vertical change (rise) to the horizontal change (run) between two points.
What does a negative slope mean?
A negative slope means the line goes downward from left to right. A positive slope goes upward, zero slope is horizontal, and undefined slope is vertical.
