Question
### Solving a System of Equations by Table

To solve the system of equations using a table, consider the following two equations:

1. \( y = \frac{3}{2}x + 4 \)
2. \( y = -\frac{1}{2}x - 4 \)

#### Table of Values
Below is a table with selected values of \( x \), and their corresponding \( y \) values from both equations:

| \( x \) | \( Y_1 \) | \( Y_2 \) |
|--------|------|------|
| -5     | -3.5 | -1.5 |
| -4     | -2   | -2   |
| -3     | -0.5 | -2.5 |
| -2     | 1    | -3   |

#### Explanation

- **Find a common \( y \)-value**: Look for the \( x \) where both \( y_1 \) and \( y_2 \) have the same value.
- In the table, when \( x = -4 \), both \( y_1 \) and \( y_2 \) equal \(-2\).

Thus, the ordered pair \((-4, -2)\) is a solution that works for both equations in the system.
