He creates a scatter plot to show the data. The regression line shown on the graph best models the data on the scatter plot. Based on the given model, how many hours in the week before the test does Jesse need to study to get a score of 90 on the test? Round your answer to the nearest hour.

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
