#(-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.
