Aditya is a Class IX student residing in a village. One day, he went to a city Hospital along with his grandfather for general checkup. From there he visited three places- School, Library and Police Station. After returning to his village, he plotted a graph by taking Hospital as origin and marked three places on the graph as per his direction of movement and distance. The graph is shown below:
(i) What are the coordinates of School?
(3,2)
(2,3)
(3,5)
(5,3)
(ii) What are the coordinates of Police Station? (a)(2,-1) (b) (2,1) (c) (-2,-1) (d) (-2,1)
(2,-1)
(2,1)
(-2,-1)
(-2,1)
(iii) Distance between school and police station:

Given : Aditya is a Class IX student residing in a village. One day, he went to a city Hospital along with his grandfather for general checkup. From there he visited three places- School, Library and Police Station. After returning to his village, he plotted a graph by taking Hospital as origin and marked three places on the graph as per his direction of movement and distance.
To Find : What are the coordinates of School
What are the coordinates of Police Station?
Distance between school and police station:
coordinates of Library
Solution:
HOSPITAL (0,0)
POLICE STATION ( 2 , - 1)
SCHOOL ( 2 , 3)
LIBRARY ( 6 , 2)
coordinates of School ( 2 , 3)
coordinates of Police Station = ( 2, - 1)
Distance between school and police station:
( 2 , - 1) and ( 2 , 3)
Distance = 3 - (-1) = 4 units
coordinates of Library ( 6 , 2)
the point (-1,4) lies in 2nd Quadrant ||
