Question

in which quadrant A(-a,-b) lies where a is small then 0 and b is greater than 0 .​

Answer 1

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.

Answer 2

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.
