Question
A zoologist studied the running speeds of animals in terms of the animals' body lengths. The results of the study are shown in the table below. (A graphing calculator is recommended.)
Body length (in centimeters), x 1 9 15 16 24 25 60
Running speed (in meters per second), y 1 2.5 7.5 5 7.4 7.6 20
(a)
Use the points (9, 2.5) and (60, 20) to find a linear model that will predict the running speed of an animal with a body length of x centimeters. (Round your coefficients to three decimal places.)
