A pediatrician records the age x (in yr) and average height y (in inches) for girls between the ages of 2 and 10. a. Use the points (2, 35) and (6, 46) to write a linear model for these data. b. Interpret the meaning of the slope in context. c. Use the model to forecast the average height of 11-yr-old girls. d. If the height of a girl at age 11 is 90% of her full-grown adult height, use the result of part (c) to estimate the average height of adult women. Round to the nearest tenth of an inch. Height of Girls vs. Age 60 50 40 |(6, 46) 30 |(2, 35) 20 10 4 10 12 Age (yr) Height (in.) 2.
