NCERT Exemplar Solution for Class 9 Maths Chapter 4 – Linear Equations in Two Variables
The fourth chapter of Class 9 Mathematics, Linear Equations in Two Variables, is an important topic that strengthens algebraic and graphical problem-solving skills. This chapter introduces students to equations involving two variables, their solutions, and representation on the Cartesian plane. With the support of NCERT Exemplar Class 9 Maths Solutions, learners can practice higher-order questions and improve their logical reasoning. The chapter begins with the general form of a linear equation in two variables, expressed as ax + by + c = 0, where a, b, and c are real numbers, and a and b are not zero. Students understand that such equations have infinitely many solutions. Through NCERT Solutions for Class 9 Maths, learners practice substituting values to verify solutions and plotting them on a coordinate plane.
A key subtopic is graphical representation of linear equations. Students learn how to draw a straight line by plotting points that satisfy a given equation. The concept of a line being the graphical representation of all possible solutions is explained in detail. Exemplar questions help students develop accuracy in plotting and interpreting graphical solutions. Another important area of focus is solving problems based on linear equations in two variables. These include word problems from real-life contexts such as speed and distance, age-related problems, and problems on money transactions. By applying equations to practical situations, students strengthen their mathematical reasoning. The chapter also introduces applications of linear equations in daily life, such as finding solutions to equations representing different conditions in business, finance, and geometry. Through NCERT Exemplar Class 9 Maths Solutions, learners get practice with non-routine problems that enhance higher-order thinking skills. By the end of the chapter, students are able to form linear equations from problem statements, represent them graphically, and interpret their solutions correctly. The NCERT Solutions for Class 9 Maths ensure that each step of the solution process is explained clearly, making it easy to follow. In conclusion, Chapter 4 builds a strong foundation in algebra and connects it with coordinate geometry. Mastering this chapter helps students prepare for higher-level topics such as pairs of linear equations in two variables, inequalities, and applications in advanced mathematics.
