Final answer:
The correct slope is 3, which means for every 1 week, Todd's savings increase by 3 dollars. The correct option is not fully provided, but analysis is based on the slope information from Figure A1.
Step-by-step explanation:
The statement that identifies the correct slope and the correct interpretation of the slope for this situation is not entirely clear due to missing options. However, based on the provided information in Figure A1 Slope and the Algebra of Straight Lines, we know that the line has a slope of 3. This indicates for every 1 unit increase on the x-axis (horizontal axis), there is a rise of 3 units on the y-axis (vertical axis). If this graph represents Todd's savings, the slope would indicate Todd's savings rate in terms of dollars per week.
Assuming we are using this same interpretation for Todd's savings, then a slope of 3 would mean Todd saves 3 dollars every week since the slope indicates how much the dependent variable (amount saved) changes for every unit increase of the independent variable (time in weeks).
