Question

. Do as directed;
1) which is not the solution of X - Y = 0​

Answer 1

Correct question:

Which is not the solution of X-Y = 0

1. (1,1)
2. (-1,1)
3. (1,-1)
4. (1,0)

Solution:

Given:

The equation X-Y = 0

To find:

The points which do not satisfy the given equation

Calculation:

Substitute the given points in the equation. If the point satisfies the given equation then the point is a solution of the equation

1. (1,1)

  =>  X-Y = 0

          1-1 = 0

           0 = 0

  (1,1) is one of the solution of the equation X-Y = 0

2. (-1,1)

  =>  X-Y = 0

         -1-1 ≠ 0

          -2 ≠ 0

 (-1,1) is not the solution of the equation X-Y = 0

3. (1, 1)

  =>  X-Y = 0

          1+1 ≠ 0

            2 ≠ 0

 (1,-1) is not the solution of the equation X-Y = 0

4.. (1,0)

  =>  X-Y = 0

         1-0 ≠ 0

            1 ≠ 0

 (1,0) is not the solution of the equation X-Y = 0

(-1,1), (1,-1), (1,0) are not solutions of the equation X-Y = 0
