Select two statements that are true about the lines that Jaxon and Fisher fit to the data.

• The data points show a positive correlation and both Jaxon and Fisher fit an increasing linear function to the data.

• The data points show a negative correlation and both Jaxon and Fisher fit a decreasing linear function to the data.

• Jaxon's line models the data better than Fisher's line because all the data points fall on or below Jaxon's line.

• Fisher's line models the data better than Jaxon's line because Fisher's line is closer to more data points than Jaxon's line is

• Jaxon's line models the data better than Fisher's line because Jaxon's line actually passes through more data points than Fisher's line passes through.

Does Mia's model represent a good fit for the data? Explain why or why not.

• Yes, because the data shows a negative linear association among the data, and Mia's model is a decreasing linear function.

• Yes, because the data shows a positive linear association among the data, and Mia's model is a decreasing linear function.

• No, because the data shows a positive linear association among the data, but Mia's model is represents the best line of best fit.

• No, Mia's increasing linear function matches the positive association of the data, but the line is not close enough to all the data points.

Which of the following conclusions about the points scored and hours practiced is best supported by the scatter plot above?

• The team needs to practice 5 hours a week.

• The team will score the most points if they practice 9.5 hours every week.

• When the team practiced more hours per week, they scored more points overall.

• There appears to be no relationship between the number of hours the team practices and the points they score.
