MCQ of Chapter 3 Maths Class 10

This chapter is all about the algebraic expression of two variables related to each other. Both variables are represented using two individual English letters. They are then set on an equation with coefficients to explain their mathematical relationships and to plot the equation on a Cartesian coordinate plane.

This chapter holds immense importance in the conceptual development of variables and equations. Based on its implications, students will proceed to learn advanced concepts at the higher secondary level of education.

This chapter covers the following topics:

• Algebraic solution

• Basic and advanced concepts about straight lines

• Revision of the basic concepts

• Graphical solution of straight lines

• Solving linear equations with coordinate geometry

As we can see, this chapter is all about the relationship between two variables in a linear format. The term ‘linear’ means the power of two variables is 1. Both variables are represented by two axes intersecting each other at the origin. Points are plotted to find the solutions graphically. Two linear equations can also be solved by using algebraic and mathematical principles.
