The problem asks to solve the system of equations:

1. \( y = -2|x + 1| + 3 \)
2. \( y - x = 1 \), or equivalently, \( y = x + 1 \)

We need to find all points \((x, y)\) that satisfy both equations.

### Step 1: Set the two equations equal to each other.
From the second equation, we know \( y = x + 1 \). Substitute this into the first equation:
\[
x + 1 = -2|x + 1| + 3
\]

### Step 2: Solve the absolute value equation.
We now have two cases based on the absolute value.

#### Case 1: \( x + 1 \geq 0 \), so \( |x + 1| = x + 1 \)
\[
x + 1 = -2(x + 1) + 3
\]
Expanding:
\[
x + 1 = -2x - 2 + 3
\]
\[
x + 1 = -2x + 1
\]
Subtract 1 from both sides:
\[
x = -2x
\]
Add \(2x\) to both sides:
\[
3x = 0 \quad \Rightarrow \quad x = 0
\]
Substitute \( x = 0 \) back into \( y = x + 1 \):
\[
y = 0 + 1 = 1
\]
Thus, one solution is \( (0, 1) \).

#### Case 2: \( x + 1 < 0 \), so \( |x + 1| = -(x + 1) \)
\[
x + 1 = -2(-(x + 1)) + 3
\]
Expanding:
\[
x + 1 = 2(x + 1) + 3
\]
Simplifying:
\[
x + 1 = 2x + 2 + 3
\]
\[
x + 1 = 2x + 5
\]
Subtract \(x\) from both sides:
\[
1 = x + 5
\]
Subtract 5 from both sides:
\[
x = -4
\]
Substitute \( x = -4 \) back into \( y = x + 1 \):
\[
y = -4 + 1 = -3
\]
Thus, another solution is \( (-4, -3) \).

### Step 3: Verify possible points from the list.
- \( (-2, 1) \): Not a solution.
- \( (-1, 2) \): Not a solution.
- \( (0, 1) \): Is a solution.
- \( (2, -3) \): Not a solution.
- \( (-4, -3) \): Is a solution.
- \( (-3, -4) \): Not a solution.

### Final Answer:
The points that are solutions to the system are:
- \( (0, 1) \)
- \( (-4, -3) \)
