A linear function is a simple mathematical model used by economists and mathematicians. When this model is graphically represented, it makes a straight line. Due to this characteristic, this model is easy to handle and understand by experts. The linear function consists of simple constants and one independent and one dependent variable.

Formula of Linear Function:

y=mx + b

where

 

y= dependent variable

x= independent variable

b= constant term

m= coefficient of the independent variable which determines the rate of change in y.
