Worksheet solutions for chapter: Coordinate Geometry for class 9 are provided below.
(1) Plot coordinates (0,0), (-5, -2) on the Cartesian plane.
The given coordinates are plotting on the Cartesian plane.
Scale for x-axis and y-axis
Let 1 cm = 1unit
Hence, point O represents coordinates (0,0) and point A represents coordinates (-5, -2).
(2)Write the answer with the help of figure given below-
(i) Write the coordinate of point A.
(ii) Write the name of the point with coordinate (-2, 3).
(iii) Write the x coordinates of the point B.
(i) The coordinates of point A is (4, 3).
(ii) The point with coordinates (-2, 3) is C.
(iii) The x coordinates of the point B is 2.
(3) Fill in the blanks:-
(i) The y-axis coordinate is called …….
(ii) The coordinate of the origin is …….
(iii) The coordinates of a point are of the form (+, +) lies in ….. quadrant.
Fill in the blanks:-
(i) The y-axis coordinate is called ordinate.
(ii) The coordinate of the origin is (0,0).
(iii) The coordinates of a point are of the form (+, +) lies in I quadrant.
(4)Identify in which quadrant coordinates lie? Give reason in your support.
(8, 9), (-3, -4), (2, – 4), (-2, 6)
(5) Write abscissa and ordinate of the following coordinates
(-4, – 3), (8, 2), (4, -5), (7, 6).
(6) Your friend sends you location of his home as in following diagram.
How you will reach to his home?
According to the diagram, my friend lives in North-East direction. He showed a XYZ Public School at origin.
(i) First, I will reach to the origin, ie, XYZ Public School.
(ii) I will move 20 m in East direction.
(iii) I will turn to a perpendicular street in North direction.
(iv) After 30 m , I will reach to my friend’s home
Choose correct answers.
(7) If x y, then
(i) (x, y) (y, x)
(ii) (x, y) =(y, x)
