The equation y=65x describes the resting heart rate of a healthy adult cow, where x represents time in minutes and y represents beats per minute. The table shows the number of times a healthy adult horse’s heart beats in different amounts of time when the animal is at rest. Which animal has the fastest heartbeat AND what is the heartbeat per 1 minute for the Adult Horse?

The horse's heartbeat  can be modeled by the regression equation

 

y = 38.26x  - 5.25     (1)

 

Because the slope  of y = 65x    is  greater than that of (1), the cow has the faster heartbeat per minute = 65 beats per minute

The heartbeat of the horse per minute  is ≈ 38 beats per minute
