NCERT Grade 9 CBSE Chapter 4 Linear Equations in Two Variables belongs to the Unit II Algebra. The Introduction describes about solving a linear equation in two variables and how does the solution look like on the Cartesian plane. The topic Linear Equations explains about the points that should be kept in mind while solving a linear problem. All these topics are explained with the help of step by step solved examples and in between exercises. The solutions given for the problems in this topic will help the students to become aware of the basic concept of linear equations.
In this chapter, students will get hold about the Solution of a Linear Equation. This topic explains a solution of a linear equation with two variables with pair of values, one for x and one for y which satisfies the given equation. All of these concepts have been taught with the help of guided examples, thus making the learning process more interactive. The solutions to the problems pertaining to the problems in between the chapters further help the students to understand their level of learning. Interesting topics such as Graph of a Linear Equation in Two Variables and Equations of Lines Parallel to x axis and y axis will be learnt in this chapter with the help of plotting the two variables of a linear equation on a graph paper. The solutions provided for all these topics are step by step so that the learner can imbibe the concept step by step.
Students are advised to go through the solutions provided in these topics for conceptual learning and scoring well in the exams.
