Question

If a < 0 & b < 0, then the point P(a, -b) lies in
​

Answer 1

Answer:

Second quadrant.

Step-by-step explanation:

Given:

a < 0.

That means,

a is a negative number.

b < 0.

That means,

b is a negative number.

Considering the point, P(a, -b) :

X - coordinate : a → Negative number.

Y - coordinate : -b → -(negative number) = Positive number.

So, the point, P(a, -b) is of the form : (negative number, positive number).

Any point of the form, ( - , + ) that is, (negative number, positive number) will lie in the second quadrant.

Therefore,

Point, P(a, -b) lies in the SECOND quadrant.
