Algebra I Recipe: Fitting a Line to Data

Given the graph below, describe the correlation.

Given the following, what is the relationship between the data?

(1, 2) (2, 3) (2, 4) (3, 5) (3, 4) (5, 6) (5, 7) (6, 8) (7, 9)

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

If a graph has a negative correlation, that means

What is the approximate slope of the best fit line for the following data:

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

What is the equation of the best fit line for the following data:
