## Important topics for RD Sharma Class 9 Maths Solutions Chapter 13 Linear Equations in Two Variables

- In RD Sharma Class 9 Maths Solutions Chapter 13, you will get to know that an equation in the form of ax+by+c=0. Here, a, b and c are real numbers, a and b are not equal to zero. Such an equation is called a linear equation.
- A linear equation which has two variables can have infinitely many solutions.
- If you plot a linear equation in two variables on a graph, you will notice that it is a straight line.
- X=0 is the equation of y-axis and y=0 is the equation of x-axis.
- You will notice that the graph of x=a is a straight line, and this line is parallel to the y-axis.
- Also, the graph of y=a is a straight line, and it is parallel to the x-axis.
- The chapter lets you know that an equation of the type y=mx represents a line that passes through the origin.
- Every point on the graph of a linear equation in 2 variables is one of the solutions of the equation. Also, every solution of the linear equation is a point on the graph of a linear equation.
