In which quadrant does the point (2,-4) lies.

The correct answer is: 4^th

Step1: For First Quadrant.
For the point to lie in the first quadrant:
The X-Coordinate must be non-negative, and the Y-Coordinate must be non-negative.
Step2: For Second Quadrant
For the point to lie in second quadrant:
The X-Coordinate must be non-positive, and the Y-Coordinate must be non-negative
Step3: For third quadrant:
For the point to lie in the third quadrant:
The X-Coordinate must be non-positive, and the Y-Coordinate also must be non-positive.
Step4: For Fourth Quadrant
For the point to lie in the fourth quadrant:
The X-Coordinate must be non-negative, and the Y-coordinate must be non-positive.
Here in the given question we can easily see that the X-Coordinate is positive and the Y-Coordinate is negative. So, the given point  lies in the  Quadrant.
