Find the rule for the following tile pattern.

tile | tile | tile | tile |

tile | tile | ||

tile |

Figure 2

tile | tile | tile | tile | tile |

Figure 4

What is the growth rate? How many tiles is each figure increasing by?

(This is the slope, or the value)

What is the starting point? How many tiles does Figure 0 have?

(This is the -intercept, or the

*value)*

Use this information to create a equation that represents the pattern.

Use the table in the eTool below to graph the rule for the tile pattern.
