Question
**Problem:**

Determine the equation of the level curves \( f(x, y) = c \) and sketch the level curves for the specified values of \( c \).

Given:
\[ f(x, y) = \frac{y}{3} \]
Values of \( c \): \( 0, 3, 5 \)

**Questions:**

1. The equation of the level curves, in terms of \( c \), is \( y = \_\_\_\_\_\_\_\_\_\).

2. Sketch the level curves for \( c = 0, 3, 5 \). Choose the correct graph below.

**Options:**

- **A.**
  - Horizontal lines at \( y = 0 \) (green), \( y = 3 \) (blue), and \( y = 5 \) (red).

- **B.**
  - Diagonal lines through the origin and points (3, 3), (6, 2), representing \( y = 3x \), \( y = 5x \).

- **C.**
  - Diagonal lines that intersect with the y-axis at \( y = 0 \) (green), \( y = 3 \) (blue), and \( y = 5 \) (red).

- **D.**
  - Vertical lines at \( x = 0 \) and lines at \( x = 3 \), \( x = 5 \).

**Graphs Explanation:**

- **Graph A:** Displays three horizontal lines indicating constant \( y \) values for \( c = 0, 3, 5 \).
- **Graph B:** Consists of diagonal lines, none representing a clear level curve for the given function.
- **Graph C:** Shows diagonal lines that move upwards, their intersections showing different values, more complex analysis needed.
- **Graph D:** Vertical lines at given \( x \) points, which do not fit the equation of level curves.

**Correct Answer Analysis:**

For the function \( f(x, y) = \frac{y}{3} \), setting it equal to \( c \) yields:
\[ \frac{y}{3} = c \]
\[ y = 3c \]

Thus, the level curves are horizontal lines where:
- For \( c = 0 \), \( y = 0 \)
- For \( c = 3 \), \( y =
