Identify the quadrant in which the point (1,−1) is located.

Select the correct answer below:

Quadrant I

Quadrant II

Quadrant III
 
Quadrant IV
Expert Solution
Step 1

In order to check weather point lies in which quadrant, we need to check signs of coordinates.

Let us consider given point is (x,y).

  • (x,y) lies in first quadrant if both x and y are positive numbers.
  • (x,y) lies in second quadrant if x  is negative number and y is positive number.
  • (x,y) lies in third quadrant if both x and y are negative numbers.
  • (x,y) lies in fourth quadrant if x is positive number and y is negative number.
