The aim of linear regression is to model a continuous variable Y as a mathematical function of one or more X variable (s), so that we can use this regression model to predict the Y when only the X is known. This mathematical equation can be generalized as follows: Y = β1 + β2X + ϵ where, β1 is the intercept and β2 is the slope.
