Given: The point is (1,-2). To find: The quadrant in which the point (1,-2) lies. Solution: We know that, In first quadrant, both coordinates are positive, i.e., (x,y). In second quadrant, x coordinate is negative but the y-coordinate is positive, i.e., (-x,y). In third quadrant, both coordinates are negative, i.e., (-x,-y). In fourth quadrant, x coordinate is positive but the y-coordinate is negative, i.e., (x,-y). Where, x and y are two non-negative values. In the given point (1,-2) the x coordinate is positive but the y-coordinate is negative. Therefore, the point (1,-2) lies in fourth quadrant. Reply

Given:The point is (1,-2).

To find:The quadrant in which the point (1,-2) lies.

Solution:We know that,

In first quadrant, both coordinates are positive, i.e., (x,y).

In second quadrant, x coordinate is negative but the y-coordinate is positive, i.e., (-x,y).

In third quadrant, both coordinates are negative, i.e., (-x,-y).

In fourth quadrant, x coordinate is positive but the y-coordinate is negative, i.e., (x,-y).

Where, x and y are two non-negative values.

In the given point (1,-2) the x coordinate is positive but the y-coordinate is negative.

Therefore, the point (1,-2) lies in fourth quadrant.
