5. a. Write the linear regression equation that models the data. b. Interpret the slope in terms of the context. c. Interpret the y-intercept. Does it have a meaning in this context? Explain your reasoning. 6. How well does the line fit the data visually? 7. What is the correlation coefficient? Does it indicate a good fit? Justify your answer. 8.
