Question 11 You are researching the growth of a species of fish. You gather a sample of fish and record the age in weeks of each fish and its mass in grams. The data is displayed on the grid below with the blue points. Age of fish (weeks) 8 12 16 20 24 28 32 Mass of fish () 100 250 400 300 700 500 850 600 You construct a linear model for the data, and your equation is y = 21.43x + 76.79 where y is the mass in grams of the fish and I is the age in weeks. a) Use the equation to identify the slope of the linear model. In the context of this problem what does the slope represent? [This box will not be graded but answers will be reviewed by your teacher.] b) Use the equation to identify the y-intercept of the linear model. In the context of this problem what does the y-intercept represent? [This box will not be graded but answers will be reviewed by your teacher. ] Question Help: Video Submit
