The graph shows the approximate U.S. box office revenues (in billions of dollars) from 2000 to 2012, where r = 0 represents the year 2000, U.S. Box Office Revenue 10 8 Revenue (billions of dollars) 2 4 6 8 10 12 x Year (0 2000) a. Estimate the slope and y-intercept of the graph. Slope: y-intercept: 36 b. Interpret your answers in part (a) in the context of the problem. The approximate U.S. box office revenue increased by about $0.22 billion each year from 2000 to 2012 and was $4 billion in 2000. The approximate U.S. box office revenue Increased by about $0.22 billion each year from 2000 to 2012 and was $8 billion in 2000, The approximate U.S. box office revenue increased by about $0.4 billion each year from 2000 to 2012 and was $8 billion in 2000. The approximate U.S. box office revenue increased by about $4 billion each year from 2000 to 2012 and was $8 billion in year 2000. C. How can you use your answers in part (a) to predict the U.S. box office revenue in 2018? Write a linear model in slope-intercept form, then substitute 18 for y and solve for 2. O Write a linear model in slope-Intercept form, then substitute 18 for and solve for y. Multiply the slope by 18 to predict the revenue. There is no way to make a prediction because the rate of change is not constant.
