## RS Aggarwal Solutions Class 8 Maths Chapter 23 Line Graphs And Linear Graphs – Overview

• Line Graph:

A line graph is a type of graph that displays the continuous data that is changing over some time. This graph is made by joining the series of data points using a line segment consecutively.

• Linear Graph:

A linear graph is a type of graph that is drawn on a plane that connects points on the x and y-axis. This graph represents the linear relationship between two variables.

There are three types of linear graphs:

1. Single Line graph
2. Double line graph
3. Compound line graph
• Constructing A Line Graph
1. On a graph, draw two lines parallel to each other. The horizontal line is x-axis, and the vertical line is y-axis.
2. Choose an appropriate scale along the x-axis and make the points.

3. Join each point with the consecutive point using a ruler and you will obtain a graph line.
• Interpreting A Line Graph

To interpret a line graph, you have to study and analyze the data.

1. Make sense of the given data.
2. Answer queries using the given data.
3. Make predictions based on the trends.
4. Find the value of one variable given the value of the other and so on.
• Single Line Graphs

A single line graph is a graph that consists of a of a single line and shows changes over time. It is used to represent only a single data set.

• Double line Graphs

A Double line graph is a type of graph where two lines are connecting points to show a continuous change. The lines can ascend and descend in a double line graph.

There are two axes in a double graph. The occurrences and categories being compared over time are represented by the x-axis, and the scale is represented by the y-axis. A set of numbers representing the data which is organized into equal intervals is called a scale.

• Linear Graph

Linear graph is a collection of points that can form a straight line. The graph (straight line), formed while representing the relationship between the x-axis and the y-axis is called a linear graph.
