## NCERT Solutions for Class 9 Maths Chapter 3 Coordinate Geometry Exercise 3.3

Question 1.
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.
Solution:
The point (-2, 4) lies on the IInd quadrant in the cartesian plane because in point (-2, 4), x is negative and y is positive.

Again, the point (3, -1) lies on the IVth quadrant in the cartesian plane because, in point (3, -1), x is positive y is negative.

Again, the point (-1, 0) lies on the x-axis because in point (-1, 0) the value of y is zero.

Again the point (1, 2) lie on the Ist quadrant because in points (1, 2) both x and y are positive.

The point (-3, -5) lie on IIIrd quadrant in the cartesian plane because in point (-3, -5) both x and y are negative.

Question 2.
Plot the point (x, y) given in the following table on the plane, choosing suitable units of distance on the axes.

Solution:
The pairs of numbers given in the table can be represented by the points (-2, 8), (-1, 7), (0, -1.25), (1, 3), and (3, -1) we use the scale 1 cm = 1 unit on the axes.
