Explanation:

• Left Graph (Number of Typos vs Practice Time):
• The line of best fit would be a straight line that approximates the trend of the data points. Since the number of typos decreases as practice time increases (negative correlation), the line of best fit would have a negative slope. It represents the general relationship between practice time and the number of typos. For example, if we have a new data point (a new practice - time value), we can use the line of best fit to predict (roughly) the number of typos. It shows that, on average, more practice time is associated with fewer typos.
• Right Graph (Score on Final Examination vs Hours Spent Studying):
• The line of best fit would be a straight line that captures the upward - trending relationship (positive correlation) of the data points. As the number of hours spent studying increases, the score on the final examination also increases. The line of best fit can be used to predict the score for a given number of study hours. It represents the average relationship, so if a student studies for a certain number of hours (say, a non - data - point value like 4.5 hours), we can estimate their score. It implies that, on average, more study time leads to a higher exam score.

Answer:

• Left Graph: A line of best fit with a negative slope representing the average decrease in the number of typos as practice time increases. It can be used for prediction of typos based on practice time.
• Right Graph: A line of best fit with a positive slope representing the average increase in exam score as study hours increase. It can be used for prediction of exam scores based on study hours.
