### NCERT Solutions for Class 9 Maths Chapter 4

NCERT Solutions for Class 9 Maths Chapter 4 Linear Equations in Two Variables help students to understand this easy but having many applications in Mathematics. This will create a strong basic understanding of linear equations with two independent variables. Linear Equations in two variables are useful to solve many problems with two variables only. In many questions, we find this concept very helpful.

Let us discuss the sub-topics in detail.

4.1: Introduction

In this chapter, students will use the knowledge of linear equations in one variable and then it will be extended to that of two variables. Students will also get the answers to many related questions.

4.2: Linear Equations

This topic explains the representation and meaning of the linear equation. These methods can solve many problems with moths easily.

4.3: Solution of a Linear Equation

Linear equations in two variables will give values of both uniquely. Also, many linear equations are possible with infinitely many solutions because their unique solution does not exist.

4.4: Graph of a Linear Equation in Two Variables

Students have learned the algebraic solution in the previous topic for a linear equation. Now in this topic, they will study the solutions of a linear equation in two variables by the graphical method.

4.5: Equations of Lines Parallel to the x-axis and y-axis

A linear equation with one variable may be considered as an equation with two variables also. In that case, it will have infinitely many solutions. Because it will have a line parallel to the X or Y-axis. In this section, the student will draw such lines.

4.6: Summary

In this chapter, the student has studied various linear equations and their possible solutions using algebraic and graphical methods. Many problems are using these methods to get solutions.
