To determine the equation that represents the relationship between the plumber's fee \( y \) and the number of hours worked \( x \), we need to understand the components involved:

  1. There is a fixed amount paid for the house visit — this is a constant that will affect the intercept of the equation.
  2. The variable fee is determined by the number of hours worked at a certain rate.

The standard form of a linear equation is typically \( y = mx + b \), where:

  • \( m \) is the slope (rate of payment per hour),
  • \( b \) is the y-intercept (fixed amount for the house visit).

From your responses, it seems we have these options:

  1. \( y = 10x - 50 \)
  2. \( y = 50x - 10 \)
  3. \( y = 50x + 10 \)
  4. \( y = 10x + 50 \)

To choose the correct equation, you need to identify which pairing of the slope (rate per hour) and intercept (fixed visit fee) represents the situation.

  • A positive slope would suggest that Anderson earns more as he works more hours, and the intercept would represent the fixed payment.
  • If \( -50 \) or \( -10 \) is the intercept, that suggests a negative fixed fee, which is not reasonable for this context.

Based on these interpretations, if Anderson's total fee increases with hours worked and starts from a positive intercept, the best-fit option would be \( y = 10x + 50 \).
