## Abstract

The linear relation is frequently encountered in applied econometrics. Let
where

*y*and*x*denote two economic quantities, then the linear relation between*y*and*x*is formalized by:$$y={{\beta }_{1}}+{{\beta }_{2}}x$$

*β*_{l}and*β*_{2}are constants. When*β*_{l}and*β*_{2}are known numbers, the value of*y*can be calculated for every given value of*x*. Here*y*is the dependent variable and*x*is the explanatory variable.## Keywords
