To identify the equations of the lines and the solution to the system of equations, we need to analyze the given equations and points.
1. **Analyzing the Given Information**:
- The equations given include:
- \(y = 12x - 3\) (appears to be one of the lines)
- \(y = -x + 3\) (appears to be the other line)
- The points provided include:
- \((4, 1)\)
- \((4, -1)\)
- \((-1, 4)\)
- \((-4, -1)\)
2. **Identifying the Equations of the Lines**:
- **Red Line**: Based on the equation \(y = 12x - 3\) and evaluating it for point \( (4, 1) \):
- Substitute \(x = 4\): \(y = 12(4) - 3 = 48 - 3 = 45\) which does not match \((4, 1)\) or \((4, -1)\). Therefore, the first equation does not fit these points.
- **Blue Line**: The equation \(y = -x + 3\) can be checked with point \((-1, 4)\):
- Substitute \(x = -1\): \(y = -(-1) + 3 = 1 + 3 = 4\), so \((-1, 4)\) is on this line.
3. **Finding the Intersection Point (Solution)**:
- To find the intersection of the two lines, set \(12x - 3 = -x + 3\):
\[
12x + x = 3 + 3 \implies 13x = 6 \implies x = \frac{6}{13}
\]
- Substitute this value into either equation to find \(y\). Using the second equation:
\[
y = -\left(\frac{6}{13}\right) + 3 = -\frac{6}{13} + \frac{39}{13} = \frac{33}{13}
\]
- Therefore, the solution to the system of equations is \(\left(\frac{6}{13}, \frac{33}{13}\right)\).
**Summary**:
- **Red Line Equation**: \(y = 12x - 3\)
- **Blue Line Equation**: \(y = -x + 3\)
- **Solution to the System**: \(\left(\frac{6}{13}, \frac{33}{13}\right)\)
