The top graph on the right shows the daily number of workers absent from the assembly line at J. B. Davis Corporation and the  number of defects coming off the assembly line for each of 9 days. The blue line on the graph can be used to approximate the number of defects coming off the assembly line per day for a given number of workers absent.

(a)  Determine the slope of the blue line using the two points indicated with ordered pairs.

(b) Using the slope determined in part (a) and the y-intercept, 10, 92, determine the equation of the blue line.

(c)  Using the equation you determined in part (b), deter-mine the approximate number of defects for a day if 3 workers are absent. 15 defects.

(d) Using the equation you determined in part (b), approximate the number of workers absent for a day if there are 17 defects that day.
