SP.1 - SP.4 Review 2024

This shows a scatterplot.

Which equation best fits the data?

• y = 1/2 x + 5

• y = 1/2 x + 3

• y = 2x + 5

• y = 2x + 3

This graph shows a scatterplot with a linear model.

Which statement best describes the linear model?

• The linear model is a good fit because it represents a positive association.

• The linear model is a good fit because the data points are clustered near the line.

• The linear model is not a good fit because the line only goes through two data points.

• The linear model is not a good fit because the data points are not distributed evenly above and below the line.
