### Finding Parametric and Symmetric Equations of a Line

This example demonstrates how to find sets of parametric and symmetric equations for a line passing through a given point and parallel to a given vector or line. The equations use integer direction numbers.

#### Given:
- **Point:** (-5, 0, 9)
- **Parallel to the vector:** **v** = 4i + 5j - 7k

#### Task:
1. Find the parametric equations.
   - (Enter your answers as a comma-separated list in the provided box.)

2. Find the symmetric equations.
   - Options are given in mathematical form. 

#### Solutions:

##### (a) Parametric Equations
Find the parametric equations for the line. Enter your answers as a comma-separated list in the provided box.

##### (b) Symmetric Equations
Select the correct symmetric equations from the given options:
- \(4x = \frac{y}{5} = 7z\)
- \(\frac{x - 5}{4} = y = \frac{z}{7}\)
- \(\frac{x + 5}{4} = \frac{y}{5} = \frac{9 - z}{7}\)
- \(\frac{x}{4} = \frac{y}{5} = \frac{z}{7}\)

Each option provides a different relationship between x, y, and z for the line defined by the given point and parallel vector.
