### Instruction on Graphs and Equations

#### Problem 16
- **Graph Description**: The graph shows a straight line crossing the vertical axis at -4 and has a negative slope. The line passes approximately through the points (-4, 4) and (4, -4).
- **Options to identify the line's equation**:
  - a. \( y = \frac{1}{2}x - 4 \)
  - b. \( y = -2x + 4 \)
  - c. \( y = 2x - 4 \)
  - d. \( y = -2x - 4 \)

- **Equation Information Needed**:
  - \( m = \) (slope of the line)
  - \( b = \) (y-intercept of the line)
  - Equation: \( y = \underline{\hspace{2cm}} \)

#### Problem 17
- **Table**:
  - \( x \) and \( y \) values are presented in a table.
  - Values: 
    - \((-5, 0)\)
    - \((0, 25)\)
    - \((10, 75)\)

- **Equation Information Needed**:
  - \( m = \) (slope)
  - \( b = \) (y-intercept)
  - Equation: \( y = \underline{\hspace{2cm}} \)

#### Problem 18
- **Table**:
  - \( x \) and \( y \) values are presented in a table.
  - Values:
    - \((0, 0)\)
    - \((1, 60)\)
    - \((2, 120)\)

- **Equation Information Needed**:
  - \( m = \) (slope)
  - \( b = \) (y-intercept)
  - Equation: \( y = \underline{\hspace{2cm}} \)

These problems require determining the equations of lines given either a graph or a set of points.
