Linear Regression Formula
Equation of the best-fit line.
ŷ = β₀ + β₁x
- β₁ (Slope): Δy / Δx
- β₀ (Intercept): value of y when x=0
Example 1
Points: (1,2), (2,4), (3,6)
- Slope = 2 (y doubles as x increases by 1)
- Intercept = 0
- Equation: y = 2x
How to Use
- Enter X values.
- Enter corresponding Y values.
