Samantha’s parents give her $10 per week. For each chore that she does not complete, she must repay her parents $1. Which graph models Samantha’s allowance?
A graph titled Samantha's Allowance has chores not completed on the x-axis and amount earned on the y-axis. A line goes through points (0, 10) and (1, 9).
A graph titled Samantha's Allowance has chores not completed on the x-axis and amount earned on the y-axis. A line goes through points (0, 10) and (2, 12).
A graph titled Samantha's Allowance has chores not completed on the x-axis and amount earned on the y-axis. A line goes through points (1, 6) and (1.5, 16).
A graph titled Samantha's Allowance has chores not completed on the x-axis and amount earned on the y-axis. A line goes through points (0, 10) and (1, 0).

To model Samantha's allowance, we need to understand how her earnings change based on the number of chores not completed.
1. Samantha starts with a base allowance of $10 each week.
2. For each chore not completed, she loses $1.
This means her amount earned (y-axis) will decrease by $1 for every chore not completed (x-axis). Thus, the relationship can be represented as:
- If no chores are missed (0 chores not completed), she earns $10.
- If 1 chore is not completed, she earns $10 - $1 = $9.
- If 2 chores are not completed, she earns $10 - $2 = $8, and so on.
Now, we look at the given options:
1. **First option**: A line through points (0, 10) and (1, 9). This indicates that when 0 chores are completed, she has $10, and when 1 chore is not completed, she has $9. This correctly models the scenario since each missed chore deducts $1 from her allowance.
2. **Second option**: A line through points (0, 10) and (2, 12). This incorrectly suggests that her allowance increases with the number of chores not completed, which does not make sense.
3. **Third option**: A line through points (1, 6) and (1.5, 16). This relationship does not accurately reflect the linear deduction based on chores not completed.
4. **Fourth option**: A line through points (0, 10) and (1, 0). This suggests that after missing just one chore, her allowance drops to $0. This would imply she owes her parents $10, which isn’t consistent with her losing $1 for each chore.
The correct graph that models Samantha's allowance is the **first option**, which accurately depicts her allowance decreasing by $1 for each chore she fails to complete.
