FAQs on NCERT Solutions for Class 8 Maths Chapter 15 Introduction to Graphs

1. What are the five essential things that a graph needs?

There are five important things that students should keep in mind while drawing a graph, and they are:

Axes and Background
Grid lines
Visual structures
Scales and tick marks
Text

2. What are the crucial elements of a useful graph?

Among different important elements, five principal features are explained below:

The experiment which describes the title
The graphical representation should fill the space allocated for the graph
