Question

Which quadrant does (-1, -2) lie?

Answer 1

`(-1,-2)` lies in third quadrant.

Explanation:

In any given coordinates `(x,y)`, the sign of abscissa i.e, `x` coordinate and the sign of ordinate i.e. `y` coordinate, both together decide the quadrant in which the pont lies.

If both `x` and `y` are positive, the point lies in first quadrant;

if `x` coordinate is negative and `y` coordinate is positive, the point lies in second quadrant;

if both `x` and `y` are negative, the point lies in third quadrant; and

if `x` coordinate is positive and `y` coordinate is negative, the point lies in fourth quadrant.

Graphically it can be shown as in image below.

In `(-1,-2)` as both `x` and `y` are negative, the point lies in third quadrant.
