Linear Equations in Two Variables

  • Linear equation in two variables:

An equation of the form, ax + by + c = 0, where a, b and c are constants, such that a and b are both not zero and x and y are variables is called a linear equation in two variables.

For example, 2x + 3y + 10 = 0, 3x + 7y = 0


  • Real life situations can be expressed mathematically as linear equations in two variables.
