## NCERT Solutions For Class 8 Maths Chapter 15 Introduction To Graphs In Hindi

Applications of graphs

There are two types of variables: Independent And Dependent, depending on how the value of one variable varies with respect to another. An Independent (or control) variable is a variable whose value does not change with respect to another quantity. A Dependent variable is a variable that changes its value in relation to another quantity. For example, consider electricity usage and electricity bills. Power consumption is an Independent variable because it does not depend on other variables. However, the electricity price is the Dependent variable as it can change in relation to the amount of electricity consumed. Charts help visually establish the relationship between these two types of variables using the Cartesian plane.

Not only in Mathematics but in almost every field, graphs are important means of storing, analysing and representing information. The next step in any research paper or survey is organising their observations and information and plotting them on graph paper or a flat surface.
