Using this graph of a linear equation as an example, create a real-world situation that the graph could model. In 3–5 sentences, explain what the graph is modeling.

The graph depicts a linear equation where the x-axis represents time (in days) and the y-axis represents the number of hours spent studying for a test. The line has a positive slope, indicating that as time increases, so does the number of hours spent studying. This graph could model the situation of a student preparing for a final exam over a period of time, where the student gradually increases the amount of time dedicated to studying each day.
