### Understanding the Diagram of Intersecting Lines

**Description:**

The diagram features two vertical lines labeled \(a\) and \(b\), and two horizontal lines labeled \(p\) and \(q\). The vertical lines intersect with the horizontal lines, creating a grid of numbered regions.

**Detailed Explanation of the Diagram:**

1. **Lines:**
   - **Vertical Lines:** There are two vertical lines, \(a\) and \(b\).
     - Line \(a\) intersects with lines \(p\) and \(q\), dividing the area into several regions.
     - Line \(b\) also intersects with lines \(p\) and \(q\), replicating a similar division.
   - **Horizontal Lines:** There are two horizontal lines, \(p\) and \(q\).
     - Line \(p\) intersects with lines \(a\) and \(b\).
     - Line \(q\) intersects with lines \(a\) and \(b\).

2. **Intersections and Numbered Regions:**
   - The intersection points divide the space into smaller, numbered areas. These numbers aid in identifying specific regions created by the intersection of these lines.
     - Above line \(p\) and to the left of line \(a\) is region 1.
     - Directly adjacent to 1 is region 2, still above \(p\) and to the left of \(a\).
     - Keeping above \(p\) but moving to the right of \(a\) is region 3.
     - Adjacent to region 3 and ending the first row, above \(p\) and to the right of \(b\) is region 4.
     - Below \(p\) but to the left of \(a\), we find regions 5 and 6.
     - Below \(p\) but to the right of \(a\), regions 7 and 8 are located.
     - Below the line \(q\) and to the left of line \(a\) are regions 9 and 10.
     - Lower and to the right of line \(a\), but left of line \(b\), is regions 11 and 12.
     - The next quadrants formed, below line \(q\) and left of \(a\) are regions 13 and 14.
     - The regions below line \(q\), between \(

This text provides a set of mathematical expressions and a piece of information about parallel lines, to be used as a basis for solving specific questions in an educational context.

- **Given:**
  - \( p \parallel q \)
  - \( m \angle 2 = 8x + 14 \)
  - \( m \angle 4 = 13y + 19 \)
  - \( m \angle 12 = 15y + 5 \)
  - \( m \angle 13 = 10x - 10 \)

Use this information to answer Questions 13 and 14.

### Explanation:

1. **\( p \parallel q \)**: This states that line \( p \) is parallel to line \( q \). This implies that alternate interior angles, corresponding angles, and consecutive interior angles formed by a transversal with these parallel lines are congruent or supplementary.

2. **\( m \angle 2 = 8x + 14 \)**: This gives the measure of angle 2 in terms of the variable \( x \).

3. **\( m \angle 4 = 13y + 19 \)**: This gives the measure of angle 4 in terms of the variable \( y \).

4. **\( m \angle 12 = 15y + 5 \)**: This gives the measure of angle 12 in terms of the variable \( y \).

5. **\( m \angle 13 = 10x - 10 \)**: This gives the measure of angle 13 in terms of the variable \( x \).

To proceed with questions 13 and 14, one would likely need to use the properties of parallel lines and the given angle measures to find specific values for \( x \) and \( y \), or to determine relationships between the angles.
