Introduction
Graphs are nothing but scale-wise plotting of big data in structured matter. You are already aware of graphs from the lower classes.
In this chapter, we will particularly talk about different types of graphs. They are as follows:
A bar graph is used to show a comparison among.
A pie graph is used to compare the different parts of a whole circle.
A histogram is a bar graph that shows data in intervals.
A line graph shows data that changes continuously.
Students can read more about different types of graphs and their real-life applications from our NCERT Solutions for Class 8 Mathematics Chapter 15, available on the Extramarks website.
Linear graphs
A number of line segments are joined together to form a linear graph. There are different steps to plotting linear graphs. They are as follows:
- Finding the location of a point
- Plotting its required coordinates
Students need to specifically find a point on the graph using scales. Then they can plot the obtained coordinates on the graph. In this way, linear graphs are plotted.
For students to better understand the working of linear graphs, we have provided multiple examples with illustrations of actual scenarios in our NCERT solution study materials. Register on the Extramarks website to get full access to our NCERT Solutions for Class 8 Mathematics Chapter 15.
Some applications
A number of dependent and independent variables are associated with the graph plotting. Based on it, there are various applications for plotting a graph. They include:
- Quantity and Cost
- Principal and Simple interest
- Time and Distance
Students can easily solve these sums using the dependent and independent variables and jump to conclusions. Thus, it makes graphical problems easy and approachable.
This section is the most important in our NCERT Solutions for Class 8 Mathematics Chapter 15 as it covers a lot of applications-oriented examples of using various forms of graphs.
