## Pages: 106-107. 9.2: Patterns in a Table of Values.

Question #1:

Graph the ordered pairs in the table of values.

Circle the table(s) of values that show a linear relation. Explain your answer.

Chart A had a linear realtion because it increases by the same amount each time. For example:

*l*- 2 + 2 = 4, 4 + 2 = 6, etc.

*m*- 7 + 2 = 9, 9 + 2 = 11, etc.
