Westland Workers Union’s Health and Wellness Department started a voluntary lunchtime running club. Members kept track of how much they ran each week for exercise and how much their resting heart rate dropped over several weeks. The data is in your text book. Note that a negative heart rate change is actually a gain in heart rate.
Make a scatterplot of the data and draw a line of best fit.
Find the equation of the line of best fit. Write your equation in slope intercept form
Use the equation to predict the heart rate change for an employee who ran 10 miles a week.
Interpret the slope and y‑intercept in this situation. Hints: what does the unit rate represent and what does the value of the yintercept mean?
