# NCERT Solutions for Exercise 4.4 Class 9 Maths Chapter 4 - Linear Equations in Two Variables

NCERT Solutions for Class 9 Maths exercise 4.4 which is based on the geometrical depiction of equations of lines parallel to the x-axes and y-axes and covers the concept of linear equations in two variables. Linear equations in two variables are a system of equations that can have a single solution, no solutions, or an unlimited number of solutions and are of the type ax+by+c=0, where a, b, c are real numbers. To identify the set of solutions to the linear equations with two variables, we must first determine the value of variables. The graphical depiction of equations of lines parallel to x-axes and y-axes was the topic of exercise 4.4 Class 9 Maths. A line parallel to the y-axis will have the form x=k, which means that the value of x is the same for any value of y , and k is any constant value. Similarly, A line parallel to the x-axis will be of the form y=k, which means that the value of y is the same for any value of x, and k is any constant value.

** Linear Equations In Two Variables Class 9 Maths Chapter 4 Exercise: 4.4 **

** Q1 (i) ** Give the geometric representations of as an equation

in one variable

### ** Answer: **

Equation can be represented in one variable on the number line.

** Q1 (ii) ** Give the geometric representations of as an equation: in two variables

### ** Answer: **

For 2 variable representations of .

Equation :

For graph,

x=0,we have y=3

x=1,we have y=3

x=2,we have y=3

Hence, (0,3) ,(1,3) and (2,3) are solutions of equation.

** Q2 (i) ** Give the geometric representations of as an equation: in one variable

### ** Answer: **

Equation can be represented in one variable on the number line.

The yellow mark represents x= - 4.5.

** Q2 (ii) ** Give the geometric representations of as an equation: in two variables

### ** Answer: **

For 2 variable representations of .

Equation :

For graph,

y=0,we have

y=1,we have

y=2,we have

Hence, , and are solutions of equation.

**More About Ncert Solutions For Class 9 Maths Exercise 4.4**

To solve linear equations in two variables visually in Class 9 Maths chapter 4 exercise 4.4, we must first construct the graph of the equations by constructing a table for various x and y values. After that, we must use the values to plot the points on the graph for each equation. We'll be able to connect all of the locations at that moment. As a result, the graph is created. We can describe the graph of linear equations in two ways in exercise 4.4 Class 9 Maths.

• A one-variable linear equation with a solution represented by a point that can be plotted on a number line.

• The solution to a two-variable linear equation that can be plotted on the cartesian plane is represented by a line parallel to the x or y-axis.

If the constant term ‘c’ in the linear equation ax+by+c=0 is zero, the line will always pass through the origin.
