(b) (-1, 1)
(d) (1,0)
(c) (1,-1)​

Answer 1

Answer:

a

the answer is a

1-1=0

Answer 2

Answer:

the question is wrong....

Step-by-step explanation:

th question should be like:

which is the solution for X-Y=0

and then the answer will be option a 1-1=0

because

-1-1=2

1-0=1

1-(-1)=1+1=2

so none of the option stands for X-Y=0

so the que is wrong....
