A random sample of students who ride the bus or walk from home to school are surveyed. Two scatter plots are created from the data. The conclusions below are based on those scatter plots. *As the distance from home increases, the number of times a week a student rides the bus to school increases. *As the distance from home increases, the number of times a week a student walks to school decreases. Which set of statements about one of the scatter plots is most likely true?

• The x-axis represents the number of times a week a student walks to school, and the y-axis represents the distance from home. The line of best fit has a positive slope.

• The x-axis represents the number of times a week a student rides the bus to school, and the y-axis represents the distance from home. The line of best fit has a negative slope.

• The x-axis represents the distance from home, and the y-axis represents the number of times a week a student walks to school. The line of best fit has a negative slope.

• The x-axis represents the distance from home, and the y-axis represents the number of times a week a student rides the bus to school. The line of best fit has a negative slope.
