The linear equations are in the form of ax + by + c = 0. When we see the linear equations, then they are in the form of a straight line. In the above equation, a, b, & c are real numbers, in which a & b are not equal to zero. At the same time, x & y are the two variables. And c is the constant.
When two linear equations are with each other, they are considered a pair of linear equations. In which both x & y terms are different from every equation.
There are also some graphical methods to represent the linear equations in two variables. All these methods are discussed below:
