Step-by-step explanation:
Given : There is a square park ABCD in the middle of Saket colony in Delhi. Four children Deepak, Ashok, Arjun and Deepa went to play with their balls. The colour of the ball of Ashok, Deepak, Arjun and Deepa are red, blue, yellow and green respectively.
To Find : the coordinates of the ball of Ashok
the coordinates of the ball of Deepa
line XOX' is called
point O (0,0) is called
ordinate of the ball of Arjun
Solution:
the coordinates of the ball of Ashok is ( 3 , 4)
Correct option is b) ( 3 ,4 )
the coordinates of the ball of Deepa is ( 2, - 3)
Correct option is a) ( 2 , -3 )
line XOX' is called is x - axis
Correct option is c. x-axis
point O (0,0) is called Origin
Correct option is d. origin
coordinate of the ball of arjun = (-3 , -3)
Abscissa = - 3 , ordinate = - 3
ordinate of the ball of Arjun is - 3
Correct option is a. -3
