Question
**Consider the Initial Value Problem**

\[
\frac{dx}{dt} = \begin{bmatrix} -2 & -2 \\ 2 & -2 \end{bmatrix} x, \quad x(0) = \begin{bmatrix} 8 \\ 2 \end{bmatrix}
\]

**(a)** Find the eigenvalues and eigenvectors for the coefficient matrix.

\[
\lambda_1 = \boxed{}, \ \vec{v}_1 = \begin{bmatrix} \boxed{} \\ \boxed{} \end{bmatrix}, \quad \text{and} \quad \lambda_2 = \boxed{}, \ \vec{v}_2 = \begin{bmatrix} \boxed{} \\ \boxed{} \end{bmatrix}
\]

**(b)** Find the solution to the initial value problem. Give your solution in real form.

\[
x(t) = \begin{bmatrix} \boxed{} \\ \boxed{} \end{bmatrix}.
\]

**Use the phase plotter pplane9.m in MATLAB to help you describe the trajectory:**

An ellipse with clockwise orientation

**1.** Describe the trajectory.
