# Simple Linear Regression (ML\_R\_1)

It uses a linear technique to predict the value of the dependent variable based on the value of the independent variable. 

The values of the coefficients of the equation are found by minimizing the difference between the observed values of the dependent variable and the predicted values by the equation. 

It can help understand the relationship between two variables and make
