We will find the solution by trying all the options.

Let point be i.e., and

Then,

Or x – y = – 1 ≠ 0

Therefore, does not satisfy x – y = 0

Let point be i.e., and

Then,

Or x – y =

Or x – y = 3 ≠ 0

Therefore, does not satisfy x – y = 0

Let point be i.e., x = 0 and y = – 1

then, x – y = 0 + 1 = 1≠0

Therefore, does not satisfy x – y = 0

Let point be i.e., x = 1 and y = 1

then, x – y = 1 – 1 = 0

Therefore, satisfies x – y = 0

Hence, the graph of the linear equation x – y = 0 passes through the point (1, 1)
