Question
**Question:**
Which number line represents the solution to the inequality \(-14x - 15 \geq 27\)?

**Number Line Options:**

- **A**  
  - Interval shown is from less than \(-10\) to 10.
  - Arrow starting from \(-3\), including it (solid dot), extends to the left.

- **B**  
  - Interval shown is from less than \(-10\) to 10.
  - Arrow starting from \(3\), not including it (open dot), extends to the left.

- **C**  
  - Interval shown is from less than \(-10\) to 10.
  - Arrow starting from \(0\), including it (solid dot), extends to the right.

- **D**  
  - Interval shown is from less than \(-10\) to 10.
  - Arrow starts from \(-3\), including it (solid dot), extends to the right.

**Explanation:**
To determine which number line represents the solution, solve the given inequality \(-14x - 15 \geq 27\).

1. Add 15 to both sides:
   \(-14x \geq 42\)

2. Divide by \(-14\), remembering to reverse the inequality sign:
   \(x \leq -3\)

The solution is \(x \leq -3\), which corresponds to option **A**, where the arrow starts from \(-3\) (inclusive) and extends to the left.
