Final answer:
To determine the best equation to model movie earnings over time, compare the options with a linear equation's structure, y = mx + b. Without a provided graph, we can't give a precise answer, but the correct equation should mirror a consistent change in earnings represented by a linear function.
Step-by-step explanation:
To find which equation best models the information given by the movie earnings graph, we need to identify the equation that correctly represents the relationship between the amount of money earned (y) each week after its release (x). Typically, this type of problem is represented by a linear equation of the form y = mx + b, where m is the slope and b is the y-intercept.
From the options provided, we can eliminate any equation that doesn't fit this format. Since no graph was provided, we will assume that the information would have suggested a straight line graph, indicating a consistent increase or decrease in movie earnings over time. Based on the solve from the Practice Test 4 Solutions, a linear equation similar to these models would be the correct type of equation to choose from the options listed.
Without the actual graph, we cannot definitively select the correct equation from the provided options. However, recall that every actual linear equation will have a constant rate of change (slope) and a starting value when x is 0 (y-intercept), and this should match the movie earnings pattern described.
