A.3.8.2 Never Know How Far You’ll Go

Priya takes note of the distance the car drives and the time it takes to get to the destination for many trips. What do the slope and y-intercept for the line of best fit mean in this situation?

Based on the correlation coefficient of r = 0.99, how would you describe the strength of the linear relationship?

How long do you think it would take Priya to make a trip of 90 miles if the linear relationship continues? If she drives 90 miles, do you think the prediction you made will be close to the actual value? Explain your reasoning.
