If x is not equal to y ,then (x,y) is not equal to (y,x),But if x is equal to y,then .......?

This was a question in MCQ in my SA-1.I wrote (x,y) = (-y,-x)

Pls help!.....With explanation.

Hi smirthy,

  • When x is equal to y (x,y) will be equal to (y,x)
  • However it is not equal to (-y,-x)
  • I will show you one example

x = 2

y = 2

(2,2) = (2,2)

(2,2) Is not equal to (-2,-2) since it will be lying in third quadrant.

 

Hope this helps!!
