Linear Equations in Two Variables Class 9 Notes

Linear Equations in Two Variables Class 9 Notes – Chapter 8

Each linear equation in two variables can be defined in a straight line. To solve a system of two linear equations in two variables, we graph both equations in the same coordinate system. The equation that can be represented in the form of px + qy + r = 0 is called a two variable linear equation. [where p, q & r are real, and p & q are not 0]. For example: 2.5p + 3q = 9, x + 8y = 9, 9u – 15v = 19, etc. Linear Equations in Two Variables Class 9 Notes are provided here to help learners understand the concepts of this chapter in an easy manner.
