Coco is training for a triathlon and has been trying to increase the length of time she can hold their breath. She notices that 5 minutes after she finishes holding her breath, her heart rate has elevated like a workout as her heart works to restore oxygen to her body. She decides to study this relationship and over several weeks times holding her breath for various lengths and her heart rate 5 minutes after she resumes breathing. The linear model is y = 0.7742x + 37.6, where x = seconds and y = heart rate 5 minutes after athlete resumes breathing. The interval of days was 35 x 130 seconds and the range of heart rates fell within the interval 64 y 142. R2 = 0.9817 Write a sentence that interprets the slope of this model
