Linear Regression Calculator

Fit a least-squares regression line y = a + b·x to paired x and y values and read off the slope, intercept, or coefficient of determination (r²). Used in forecasting, trend analysis, and any setting where you want to quantify how much y changes with x.

Statistics

Linear Regression Slope Calculator

Calculate the slope of a least-squares linear regression line from summary statistics of paired x and y data. The slope tells you how much y changes per unit change in x — central to forecasting, regression analysis, and any task that quantifies a linear relationship between two variables.
