Given : X - Y  = 0

To Find : which point is not the solution

a (1,1) b (-1,1) c(1,-1) d(1,0)​

Solution:

x  - y  = 0

=> x = y

Any solution where x ≠  y is not a solution  of  x - y  = 0  

Hence b (-1,1)   c(1,-1) d(1,0)​ are not solution of x - y =  0

Verification :

b (-1,1)

-1 - 1 = - 2  ≠ 0

c (1,-1)

1 - (-1 ) = 2  ≠ 0

d (1,0)

1 -0 = 1  ≠ 0

a (1,1) is the solution

as 1 - 1 = 0 = 0

(-1,1)  , (1,-1)  , (1,0)​  are  not solution of x - y  = 0

(1,1)  is the solution
