Follow along as this tutorial uses an example to explain the solution to a system of equations. A linear relationship or linear association is a statistical term used to describe a straight-line relationship between two variables. Surprisingly when any linear equation is plotted on a graph it will necessarily produce a straight line - hence the name.

This lesson is on what a linear equation is. The line has a slope of 4 and crosses the y intercept at 3. An algebraic equation such as y 4x 3 in which the variables are of the first degree that is raised only to the first power. A linear equation is an equation where the unknowns or variables are powers with exponent one.
