Introduction to the Chapter Linear Equation in Two Variables

The conceptions resting on Linear Equations are discussed in this chapter in easy language. This chapter consists of topics like Linear Equations in two variables, the solution of a linear equation, the Graph of a linear equation in two variables and equations of lines parallel to the X-axis and Y-axis. Linear Equations are the equations of the foremost array. The linear equations are explained for the lines in the coequal system. 


If the equation has a homogeneous variable of degree 1, also it's called a linear equation in one variable. Each linear equation in two variables explains a straight line. To answer a system of two linear equations in two variables, we graph both equations in the equal coordinate network. The coordinates of any junctures that graphs hold in common are answers to the system since they solve both equations.

2. What is the overview of RD Sharma Chapter-13 Linear Equation in Two Variables?

The overview of the RD Sharma Chapter-13 Linear Equation in Two Variable is:

  • An equation of the formation ax+by-c = 0, where a, b and c are real numbers, thus and so, a and b doesn't equal to zero, is known as a linear equation in two variables. 

  • A linear equation in two variables can be deciphered into infinite results.

  • Every linear equation in two variable graphs is a linear line. 

  • The graph of x = a is a straight line aligned to the y- axis. 

  • The graph of y = a is a straight line aligned to the x-axis. 

  • An equation of the sort y = mx represents a line passing through the source. 

  • Every juncture on the graph of a linear equation in two variables is a result of the linear equation. Also, every result of the linear equation is a juncture on the graph of the linear equation. 

3. What is the importance of studying Linear equations in Two Variables?

Linear equations are a very important tool in science and also any everyday applications. This is very useful, especially for scientists, to describe relationships between two variables in the physical world, make predictions, calculate rates, and make conversions, among other things. Graphing linear equations help make trends visible.
