NCERT Class 9 Math Chapter 3 Coordinate Geometry Exercise 3.2 Solution
Exercise – 3.2
(1) Write the answer of each of the following questions:
(i) What is the name of horizontal and the vertical lines drawn to determine the position of any point in the Cartesian plane?
Ans: Horizontal line = X axis
Vertical line = Y axis
(ii) What is the name of each part of the plane formed by these two lines?
Ans: Each part of the plane formed by these two line is quadrant.
(iii) Write the name of the point where these two lines intersect.
Ans: Origin
(2) See Fig.3.14, and write the following:
(i) The coordinates of B.
Ans: Abscissa = x – coordinate = -5
Ordinate = y – coordinate = 2
Coordinates (5.2)
(ii) The coordinates of C.
Ans: Abscissa = x – coordinate = 5
Ordinate = y – coordinate = -5
Coordinate = (5; 5)
(iii) The point identified by the coordinates (–3, –5)
Ans: Abscissa = x – Coordinate = -3
Ordinate = y – coordinate = -5
So, the required point is point E.
(iv) The point identified by the coordinates (2, – 4).
Ans: Abscissa = x – coordinate = 2
Ordinate = y – coordinate = -4
So, the required point is point G.
(v) The abscissa of the point D.
Ans: Abscissa = x – coordinate = 6
Hence, abscissa of point D is 6.
(vi) The ordinate of the point H.
Ans: Ordinate = y – coordinate = -3
Hence, the ordinate of point H is – 3
(vii) The coordinates of the point L.
Ans: Abscissa = x – coordinate = 0
Ordinate = y – coordinate = 5
Coordinate = (0, 5)
(viii) The coordinates of the point M
Ans: Abscissa = x – coordinate = -3
Ordinate = Y – coordinate = 0
Coordinates = (-3, 0)
