Question

Write a function to describe the following scenario.After sprinting, Emilie has a heart rate of 160. Asshe cools down, her heart rate falls by 12 beatsper minute. What will her heart rate be after acertain number of minutes?y = [?]-[ ]]

Answer 1

Consider that the initial hear rate of 160 is a constant. Due to after each minute the hear rate decreases 12 beats, the slope of the line which describes the function is negative.

If y is hear rate and x the time in minutes, you can write:

$y=160-12x$

the previous function describes the hear rate of Emilie after x minutes.
