Answer:
as per answer a = is smaller than 0
therefore a = -a
because the number is smaller than 0 is always negative.
b = is greater than 0 is always positive
there it should be positive
and -a & -b is lies in 3 quadrant.

Step-by-step explanation:
Given:-
A(-a,-b) ,where a is smaller than 0 and b is greater than 0
To find:-
In which quadrant A(-a,-b) lies ?!
Solution:-
Given point is A(-a, -b)
If a is smaller than zero then it is a negative number.
If b is greater than zero then it is a positive number.
now ,
given that a is a negative number =-a
-(-a)=a is a positive number
and given that b is a positive number =b
-b is a negative number.
So (-a,-b) becomes (a,-b)
It lies in quadrant IV
Answer:-
A(-a,-b) lies in IV th quadrant.
Used concept:-
If x and y are the abscissa and ordinate respectively,then
- (x,y) lies in Ist quadrant.
- (-x,y) lies in II nd quadrant.
- (-x,-y) lies in III rd quadrant.
- (x,-y) lies in IV th quadrant.
