Step 1(a):
b. Model the data with a line of best fit. According to your model, how many days do you expect a cold to last for a patient taking th
supplement for 1.5 months?
Hint (b):
How long do you predict a cold will last for a person who has not taken the supplement?
Step 1(b):
Estimate the line of best fit. Remember that the equation of your line does not have to exactly match what the table
shows.
Step 2(b):
Find the y-intercept and slope to write the equation of your line.
Step 3(b):
Substitute 1.5 for .
What is the equation??
