Linear Regression is the first step to climb the ladder of machine learning algorithm. It is a good starting point for more advanced approaches and in fact many fancy statistical learning techniques can be seen as an extension of linear regression. In the most simple words Linear Regression is the supervised Machine Learning model in which the model finds the best fit linear line between the independent and dependent variable ie it finds the linear relationship between the dependent and independent variable.
