To determine which statements are true about the given system of equations, we should check each proposed point against both equations.

**Equations:**
1. \(6x - 7y = 26\) (Line 1)
2. \(2x + 9y = -3\) (Line 2)

**Checking the points:**

1. **Point \((-6, 1)\):**
- Line 1: \(6(-6) - 7(1) = -36 - 7 = -43 \neq 26\) (not a solution)
- Line 2: \(2(-6) + 9(1) = -12 + 9 = -3\) (a solution)
- **Conclusion:** \((-6, 1)\) is a solution for Line 2 only. **(True)**

2. **Point \((3, -1)\):**
- Line 1: \(6(3) - 7(-1) = 18 + 7 = 25 \neq 26\) (not a solution)
- Line 2: \(2(3) + 9(-1) = 6 - 9 = -3\) (a solution)
- **Conclusion:** \((3, -1)\) is not a solution to the system. **(False)**

3. **Point \((0, 3)\):**
- Line 1: \(6(0) - 7(3) = 0 - 21 = -21 \neq 26\) (not a solution)
- Line 2: \(2(0) + 9(3) = 0 + 27 = 27 \neq -3\) (not a solution)
- **Conclusion:** \((0, 3)\) is not a solution for either line. **(False)**

4. **Point \((-3, 1)\):**
- Line 1: \(6(-3) - 7(1) = -18 - 7 = -25 \neq 26\) (not a solution)
- Line 2: \(2(-3) + 9(1) = -6 + 9 = 3 \neq -3\) (not a solution)
- **Conclusion:** \((-3, 1)\) is not a solution for either line. **(False)**

**Summary of the truth of the statements:**
- \((-6, 1)\) is a solution for Line 2 only. **(True)**
- \((3, -1)\) is a solution to the system. **(False)**
- \((0, 3)\) is a solution for Line 1 only. **(False)**
- \((-3, 1)\) is a solution to the system. **(False)**

Thus, only the first statement is true.
