How to know a coordinate belonging to which quadrant without plotting them in the cartesian plane?

We can know that by using general forms (+ , +) in the first quadrant, (–, +) in the second quadrant, (–, –) in the third quadrant and (+, –) in the fourth quadrant

How many activities are covered before Class 9 Maths chapter exercise 4.1?

One activity is covered before Class 9 Maths chapter exercise 4.1

What is topic of activity covered before Class 9 Maths chapter exercise 4.1?

It is a game in which we will use two dice of separate colour and then we will take coordinate as number appeared on dice as there are two dices one will show x coordinate and other will show y coordinate

How to deduce the scale of the coordinate axis?

Many a scale is of 1 unit =1 centimeter but if the coordinate are bigger such as (20,90);(30,80) then scale can be of 1 unit = 10 centimeter

What does +x,+y and -x,-y depict in a coordinate plane?

+x and +y show positive real numbers and -x and -y show negative real numbers as cartesian planes have only real numbers.

Team Careers360Updated on 29 Jul 2022, 03:59 PM IST

Till now in question the points have already been marked and we have been asked to tell the coordinates but in NCERT Solutions for Class 9 Maths chapter 3 exercise 3.3. We have been given points to plot on the plane; for example, if we were given a point to plot in the cartesian plane, the first step would be to draw coordinate axes, and then we would choose a scale for the coordinate axis, such as 1 centimeter.

NCERT book Class 9 Maths exercise 3.3 is a foundation exercise for the branch of coordinate geometry as well as all of the chapters that will be covered in subsequent sessions. The following activities are included in Class 9 Mathematics chapter 3 exercise 3.3.

Coordinate Geometry Class 9 Chapter 3 Exercise: 3.1

Q1 In which quadrant or on which axis do each of the points (– 2, 4), (3, – 1), (– 1, 0),(1, 2) and (– 3, – 5) lie? Verify your answer by locating them on the Cartesian plane.

Answer:

(-2,4) lies in second quadrant

(3,-1) lies in fourth quadrant

(-1,0) lies in second quadrant

(1,2) lies in first quadrant

(-3,-5) lies in third quadrant

Q2 Plot the points (x, y) given in the following table on the plane, choosing suitable unitsof distance on the axes.

x	-2	-1	0	1	3
y	8	7	-1.25	2	-1

Answer:

So, the graph of the given points is

Benefits of NCERT Solutions for Class 9 Maths Exercise 3.3

Plotting a Point on the Plane if its Coordinates are Given is a basic concept covered in Class 9 Mathematics chapter 3 problem 3.1.
NCERT Class 9 Maths chapter 3 exercise 3.3, will be helpful in Class 10 Maths chapter 7 coordinate geometry as the chapter starts with assuming that we know how to plot points, locate them and which quadrant they belong.
Class 11 Mathematics chapter 10 straight line and Class 11 Maths chapter 11 conic section would benefit from NCERT solutions for exercise 3.3 Class 9 Maths chapter 3.
Exercise 3.3, Class 9 Maths, is also a foundation idea for several joint entrance test themes (JEE Main).
