Question

In Part 3

Write the non-arbitrary parameters in terms of the arbitrary ones.

**Part 1**

The following system of equations is row reduced.

\[
\begin{bmatrix}
1 & 0 & 0 & 0 & -4 & 10 & -9 \\
0 & 1 & 0 & 0 & 8 & -4 & 10 \\
0 & 0 & 1 & 0 & -1 & 1 & 7 \\
0 & 0 & 0 & 1 & 7 & 7 & -1 \\
\end{bmatrix}
\]

How many solutions does this system of equations have? (If it has an infinite number write **infinite**).

- **Answer:** infinite

---

**Part 2**

Which of the following are arbitrary solutions? (Note: the first column represents \(u\), the second column represents \(v\), etc.)

- A. \(w\)
  
- B. \(y\)

- C. \(u\)

- D. \(v\)

- E. \(z\)

- F. \(x\)
