Michael swam 2,000 yards on each of eighteen days. The scatterplot above shows his swim time for and corresponding heart rate after each swim. The line of best fit for the data is also shown. For the swim that took 34 minutes, Michael’s actual heart rate was about how many beats per minute less than the rate predicted by the line of best fit?

The scatterplot above shows a company’s ice cream sales d, in dollars, and the high temperature t, in degrees Celsius (.^@C) , on 12 different days. A line of best fit for the data is also shown. Which of the following could be an equation of the line of best fit?

Ten 25- year - old men were asked how many hours per week they exercise and their resting heart rate was taken in beats per minute (BPM). The results are shown as points in the scatterplot below, and the line of best fit is drawn. How many of hte men have a resting heart rate that differs by more than 5 BPM from the resting heart rate predicted by the line of best fit?

Ten 25 - years - old men were asked how many hours per week they exercise and their resting heart rate was taken in beats per minute (BPM). The results are shown as points in the scatterplot above, and the line of best fit is drawn. What is the resting heart rate, in BPM, of the men represented by the data point that is farthest from the line of best fit?

Joe bikes 4 kilometers to school . Because of the traffic and road conditions along the way , his speed varies. The dots on the graph above show his distance from the school at various times , starting at home at t=0 (black dot). After 5 minutes Joe is 3.2 kilometers from the school (second black dot). The data show that his speed is almost constant , and his distance from the school can be approximated by a straight line . The graph of the function that models Joe's distance from school as a function of time , in minutes , is shown as a solid line. Which of the following equations best represents this function ?

Ten 25- year - old men were asked how many hours per week they exercise and their resting heart rate was taken in beats per minute (BPM). The results are shown as points in the scatterplot below, and the line of best fit is drawn. Which of the following is the best interpretation of the slope of the line of best fit in the context of this problem?
