(a) Find a formula in slope-intercept form for a linear function f that models the data. f(x) = (Use integers or decimals for any numbers in the expression. Round to two decimal places as needed.) (b) Interpret the slope of the graph of y = f(x). Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal rounded to two decimal places as needed.) O A. Hours worked decreased, on average, by hours per year. O B. Hours worked increased, on average, by hours per year. (c) Estimate the annual hours worked in 2018. The annual hours worked by the average worker in 2018 would be about hours. (Round to the nearest hour as needed.)
