## Topics Covered in Exercise 13.1 Class 8 Mathematics Questions

Ex 13.1 class 8 maths chapter 13 NCERT solutions are based on solving questions related to graphs. In this exercise we will talk about a line graph.

 1 A line Graph 2 Linear Graph

Graph - Graphs are the visual representations of the collected data in a way that is easy to understand. Graphs are typically used to compare two or more data sets.

1. A line Graph - A line graph displays data that changes continuously over periods of time.

2. Linear Graph - A line graph which is a whole unbroken line is called a linear graph.

Location of a Point - The Cartesian plane is used to create a linear graph. This is the system on which the points are marked with the help of vertical lines and horizontal lines.

Coordinates of a Point - In order to write the coordinates of a point we need x-coordinates and y-coordinates of a point.

• The x-coordinate indicates the number of units to be moved either to the right or to the left. This is also referred to as the abscissa.

• The y-coordinate indicates the number of units to be moved up or down; it is also referred to as the ordinate.

• When writing coordinates in the coordinate plane of a point, we write the x-coordinate first then the y-coordinate, and then the coordinates are placed in bracket.

• The coordinates of the intersection of the x-axis and the y-axis are (0, 0), which is referred to as origin.

Question 1. What is line graph according to NCERT solutions class 8 maths chapter 13 ex 13.1?

Answer 1. A line graph displays data that changes continuously over periods of time.

Question 2. Define a linear graph?

Answer 2. A line graph which is a whole unbroken line is called a linear graph.

Question 3. What is a cartesian plane and coordinate axes?

Answer 3. A cartesian plane is formed and defined by two perpendicular number lines called  the x−axis and the y-axis. The x-axis which is horizontal and the y−axis, which is vertical are called the coordinate axes.
