To identify the solution for the system of equations given in Jian's table, we need to analyze the two equations:

1. \( y = 2x - 5 \)
2. \( y = x - 3 \)

We can determine the solution to the system by finding the point (x, y) where both equations give the same y-value.

From the table, we can observe the y-values for different x-values:

- At \( x = 0 \): \( y = -5 \) (from both equations)
- At \( x = 1 \): \( y = -3 \) (from both equations)
- At \( x = 2 \): \( y = -1 \) (from both equations)
- At \( x = 3 \): \( y = 1 \) for the first equation and \( y = 0 \) for the second equation

Now, checking these values, we see they only match at:

- \( x = 2 \): \( y = -1 \) (this is in both equations)

We can also evaluate the equations to find the intersection point analytically by setting them equal to each other:

\[
2x - 5 = x - 3
\]
\[
2x - x = -3 + 5
\]
\[
x = 2
\]

Now substituting \( x = 2 \) back into either equation to find \( y \):
\[
y = 2(2) - 5 = 4 - 5 = -1
\]

Thus, the solution to the system of equations is:

\((2, -1)\)

So the correct answer is:

**(2, −1)**
