Algebra II Recipe: Correlations and Best-Fitting Lines

By C Adams

Directions and/or Common Information:

Describe the relationship between the x and y coordinates.

(-3, -2) (-2, -2) (-1, -2) (-1, -1) (0, 0) (1, 1) (2, 1) (2, 2) (3, 3)

(-3, 2) (-2, 1) (-1, 0) (-1, 1) (0, 1) (1, 0) (1, -1) (2, -2) (3, -1) (3, -2)

Directions and/or Common Information:

Choose the best answer for each question.

If a graph has positive correlation, the graph could be best described as:

If a graph has negative correlation, that means:

What is the approximate slope for the line that best fits the following data points:

(6, 11) (8, 10) (9, 11) (9, 10) (10, 10) (10, 9) (12, 9) (12, 8) (14, 7)

Using the 2004 Hurricane Data below, what would be the best explanation for the slope of the line of best fit?
