A linear equation is made up of two expressions set equal to each other. In a linear equation in *x* and *y*, x is called *x* is the independent variable and *y* depends on it. You call *y* the dependent variable. If the variables have other names, yet do have a dependent relationship, the independent variable is plotted along the horizontal axis. Most linear equations are functions (that is, for every value of *x*, there is only one corresponding value of *y*). Presenting before you *linear equations in two variables* solver image which you should carefully observe .

What is a Linear Equation ?:

Linear equation can be understood to bea mathematical expression that has an equal sign and linear expressions

What is a Variable?

Variable is a number that you don’t know, often represented by “x” or “y”.but any letter will do!
