Y stands for the predictive value or dependent variable.

The variables (X1),(X2) and so on through (Xp) represent the predictive values,or independent variables,causing a change in Y.

The variable (b0) represents the Y-value when all the independent variables (X1 through Xp) are equal to zero.

How do I plot a regression line in Excel?
