In multiple regression you have more than one predictor and each predictor has a coefficient (like a slope), but the general form is the same: y = ax + bz + c Where a and b are coefficients, x and z are predictor variables and c is an intercept. Regression refers to a statistical that attempts to determine the strength of the relationship between one dependent variable (usually denoted by Y) and a series of other changing variables (known as independent variables). Every value of the independent variable x is associated with a value of the dependent variable y.
