2-6.

A tile pattern has five tiles in Figure 0 and adds seven tiles in each new figure. Write a linear equation that represents this pattern.* **2-6 HW eTool* (Desmos) Homework Help ✎.

Illustrate the problem.

Use the equation of a line to substitute in known information.

The equation of a line is *y = mx + b*.

*m* = the rate of growth between each figure*b* = the starting number of tiles

*y* = 7*x* + 5

Use the eTool below to write the equation of the line that represents the growth of the pattern by completing the table.
