Regression Line Formula. But remember in statistics the points don t lie perfectly on a line the line is a model around which the data lie if a strong linear pattern exists. Regression equation y a bx slope b nσxy σx σy nσx 2 σx 2 intercept a σy b σx n where x and y are the variables.
Now first calculate the intercept and slope for the regression. But for better accuracy let s see how to calculate the line using least squares regression. B 6 152 06 37 75 24 17 6 237 69 37 75 2.
Now first calculate the intercept and slope for the regression.
We can place the line by eye. Y bx a ε as you can see the equation shows how y is related to x. B the slope of the regression line a the intercept point of the regression line and the y axis. Y is the dependent variable and plotted along the y axis.
