Answer:
GIVEN :-
Ordered pairs given are :-
- (2 , -1)
- (-5 , 3)
- (4 , 3)
- (-2 , -3.5)
- (0.5 , 1.75)
TO FIND :-
- Correct quadrant for each ordered pair.
FACTS TO KNOW BEFORE SOLVING :-
- While writing the co-ordinates of a point , its ordered pair is always in the form of ( x , y ) where x = x-coordinate of the point & y = y-coordinate of the point.
- In Quadrant 1 , the coordinates of a point is always = ( +x , +y ) because Quadrant 1 lies between the positive side of x-axis & positive side of y-axis.
- In Quadrant 2 , the coordinates of a point is always = ( -x , +y ) because Quadrant 2 lies between the negative side of x-axis & positive side of y-axis.
- In Quadrant 3 , the coordinates of a point is always = ( -x , -y ) because Quadrant 3 lies between the negative side of x-axis & negative side of y-axis.
- In Quadrant 4 , the coordinates of a points is always = ( +x , -y ) because Quadrant 4 lies between the positive side of x-axis & negative side of y-axis.
SOLUTION :-
- (2 , -1) is in Quadrant 4 because it's x-coordinate is positive whereas its y-coordinate is negative.
- (-5 , 3) is in Quadrant 2 because its x-coordinate is negative but y-coordinate is positive.
- (4 , 3) is in Quadrant 1 because both its x-coordinates & y-coordinates are positive.
- (-2 , -3.5) is in Quadrant 3 because both its x-coordinates & y-coordinates are negative.
- (0.5 , 1.75) is in Quadrant 1 because both its x-coordinates & y-coordinates are positive.
