2-6.

A tile pattern has 5 tiles in Figure 0 and adds 7 tiles in each new figure. Write the equation of the line that represents the growth of 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
