 Linear equations in two Variables:

 An equation of the form ax + by + c = o where a, b, c are real numbers and (a2 + b2 ≠ 0) is called a linear equation in two variables.

 Two linear equations in two variables of the same type are called a pair of linear equations in two variables.

      a1x + b1y + c1 = 0 (a12 + b12 ≠ 0), a2x + b2 y + c2 = 0 (a22 + b22≠0); a1, a2, b1, b2, c1, c2 are real numbers
