Answer 1

To determine if the ordered pairs (1, 8) and (2.5, 20) represent different rates based on the graph of the amount of money Sal earns for babysitting, you can analyze the pairs:

• The ordered pair (1, 8) indicates that after 1 hour, Sal earns $8.
• The ordered pair (2.5, 20) indicates that after 2.5 hours, Sal earns $20.

To calculate the rate for each ordered pair:

1. For (1, 8):

   • Rate = Earnings / Hours = 8 / 1 = $8 per hour.

2. For (2.5, 20):

   • Rate = Earnings / Hours = 20 / 2.5 = $8 per hour.

Both ordered pairs represent the same rate of $8 per hour.

Based on this analysis, the correct answer is:

C. No, Sal is paid the same rate for each hour worked.
