Consider the following set of ordered pairs. Complete parts a through c. x 2 4 y a. Calculate the slope and y-intercept for these data. (Round to four decimal places as needed.)

Tell whether a linear model or a quadratic model is appropriate for the data. If linear, tell whether the slope should be positive or negative. If quadratic, decide whether the leading coefficient of x should be positive or negative. O A. linear, negative O B. quadratic; negative O C. quadratic; positive O D. linear; positive 3- 2- -5 43 2 2. 3 4 5 20 -4-

A study was done to look at the relationship between number of vacation days employees take each year and the number of sick days they take each year. The results of the survey are shown below.   Vacation Days 2 7 0 3 2 9 15 3 8 0 11 Sick Days 10 3 6 5 4 5 0 4 2 11 0   Interpret the y-intercept in the context of the question: If an employee takes no vacation days, then that employee will take 8 sick days. The y-intercept has no practical meaning for this study. The best prediction for an employee who doesn't take any vacation days is that the employee will take 8 sick days. The average number of sick days is predicted to be 8
