Free regression calculator to calculate linear regression line. Instant results in your browser — no signup. Slope m = Σ(x−x̄)(y−ȳ)/Σ(x−x̄)²; intercept b = ȳ − mx̄.
Slope m = Σ(x−x̄)(y−ȳ)/Σ(x−x̄)²; intercept b = ȳ − mx̄.
Fit a best-fit line through scattered (x, y) pairs.
Plug x into y = mx + b for predicted ŷ.
