**Mass-Spring System with Damping: Examining Motion Equations**

The motion of a mass-spring system with damping is described by the differential equation:

\[ y''(t) + b y'(t) + 9y(t) = 0 \] 

with initial conditions \( y(0) = 1 \) and \( y'(0) = 0 \).

Determine and sketch the equations of motion for different values of the damping coefficient \( b \): 0, 2, 6, and 10.

---

**Equation of Motion for Different \( b \) Values:**

- **For \( b = 0 \):**
  \[ y(t) = \_\_ \]
  *(Type the exact answer, using radicals as needed.)*

- **For \( b = 2 \):**
  \[ y(t) = \_\_ \]
  *(Type the exact answer, using radicals as needed.)*

- **For \( b = 6 \):**
  \[ y(t) = \_\_ \]
  *(Type the exact answer, using radicals as needed.)*

- **For \( b = 10 \):**
  \[ y(t) = \_\_ \]
  *(Type the exact answer, using radicals as needed.)*

---

**Graph Selection:**

Each graph represents the system's response for different \( b \) values:

- **Graph A:**
  - \( b = 0 \) is a solid blue line.
  - \( b = 2 \) is a dotted red line.
  - \( b = 6 \) is a dashed green line.
  - \( b = 10 \) is a dash-dot black line.

- **Graph B, C, and D:** (*Examine the key for line styles to determine which graph matches each description.*)

Select the graph that correctly represents all solutions based on the indicated line styles for each \( b \) value: 

- **b = 0**: Solid blue line
- **b = 2**: Dotted red line
- **b = 6**: Dashed green line
- **b = 10**: Dash-dot black line

Use this information to identify the correct graph that displays the motion equations for each damping coefficient value accurately.
