a linear function in slope intercept form (y = mx + b where m is the slope and b is the y-intercept). Describe how this could be used in the medical field assuming two data points such as:

1) hour 1, heart rate is 60

2) hours 2, heart rate is 80

Assume that whatever topic to describe (cholesterol level, heart rate, etc.) will follow a linear pattern for the purposes
