Final answer:
None of the options provided by the student represents a scenario that could be denoted by a negative integer. However, a temperature decrease, such as a cold front causing a drop in temperature by 40 degrees Fahrenheit, can be represented by a negative integer.
Step-by-step explanation:
The student is asking which statement could be represented by a negative integer. Looking at the options provided:
- Maria spent $9 at the movies doesn't imply a negative since spending money is a decrease but not a temperature or position which are commonly denoted as negative.
- Ryan has no money in his wallet isn't a negative integer, it is zero.
- A football player gained 10 yards suggests a positive increase in yardage, not a negative integer.
- The temperature outside increased by 8 degrees Fahrenheit indicates positive change as well.
However, based on the additional information provided, a situation that could be represented by a negative integer would be like the one mentioned where the temperature drops by a certain degree, such as "Suppose a cold front blows into your locale and drops the temperature by 40.0 Fahrenheit degrees." This drop in temperature is a decrease and could be represented by a negative integer.
