  1. LINEAR EQUATIONS IN TWO VARIABLESCBSE Class 9

  2. LINEAR EQUATIONS IN TWO VARIABLES • 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. The solution of a linear equation is not affected when: a) the same number is added to (or subtracted from) both the sides of the equation. b) both the sides of the equation are multiplied or divided by the same non-zero number. • A linear equation in two variables is represented geometrically by a straight line whose points make up the collection of solutions of the equation. This is called the graph of t the linear equation. The polynomial equation ax + by + c = 0 is called a linear equation because its geometrical representation is a straight line.  • To obtain the graph of a linear equation in two variables, it is enough to plot two points corresponding to two solutions and join them by a line. However, it is advisable to plot more than two such points so that you can immediately check the correctness of the graph.
