Which choice represents a line that best fits the data?

Which best describes the linear model?

• The linear model describes the data well because the points are scattered above and below the line.

• The linear model does not describe the data well because there are not the same amount of points above the line as below the line.

• The linear model does not describe the data well because it does not go through any of the points.

• The linear model describes the data well because some of the points are close to the line.

Which statement best describes the linear model?

• The linear model describes the data well because most the points are below the line.

• The linear model describes the data well because the points are not in a straight line.

• The linear model does not describe the data well because the points are not in a straight line.

• The linear model does not describe the data well because the points are not scattered above and below the line.

Which statement describes the function that would most appropriately model the data?

• a straight line with negative slope

• a straight line with positive slope

• a curved line that is increasing

• a curved line that is decreasing
