Question 1189298: . In testing an experimental diet for hens, it was determined that the average live
weight w (in grams) of a hen was statistically a linear function of the number of days d after
the diet began, where 0 ≤ d ≤ 50. Suppose the average weight of a hen beginning the diet
was 40 grams and 25 days later it was 675 grams.
(a) Determine w as a linear function of d. Clearly illustrate your steps. (20 marks)
(b) Sketch the graph of this linear function by hand. Clearly indicate the points you
used to locate this line, as well as the y-intercept of the line. (30 marks)
(c) Find the average weight of a hen when d=10. (10 marks)

rate of change is x gm/day
40 gm + x gm/day*25days=675 gm
25x=635
x=25.4 gms/day slope
---
when x=0, y=40 (y-intercept is 40 gms)
when x=5 y=167
when d=10, wt=y=294 gms
