About NCERT Class 8 Maths Chapter 15 Introduction to Graphs Exercise 15.3 

 

A graph can be used to represent the relationship between a dependent and an independent variable. Anything which is completely independent and its movement does not depend on any other factor is called an Independent Variable

 

Anything which increases or decreases with the movement of any other factor or is dependent on any other factor is called a Dependent Variable.

 

For example, the following graph shows that the revenue will increase with the increase in the number of cars washed. So, the revenue is the dependent variable and the number of cars washed is an independent variable.


 

Let us now analyse the types of questions given in Exercise 15.3 for your better understanding:

 

Ex 15.3 Q1: In this question, you are given three different tables. You have to study them and form the graphs. The first table describes the cost of apples. The second table shows the distance travelled by car and the third table shows interest in deposits for a year. You have to identify the dependent and independent variables in each while forming the graphs. 

 

Ex 15.3 Q2: In this second question, you are given two different tables. You have to draw their respective graphs and find out if the graphs are linear or not. You must know that a linear graph is a straight line graph.
