Class 9 Maths Linear Equations In 2 Variables | Introduction |

**Introduction**

An equation of the form ax + by + c = 0, where a, b and c are real numbers, such that a and b are not both zero, is called a linear equation in two variables. A linear equation in two variables has infinitely many solutions. Algebraic Equation with 1 degree of Polynomial is called Linear equation because the graphical representation is a linear line. Each point in the graph represents a solution, thus linear equation in 2 variables has multiple solutions.
