5-5.

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

$y=7x+5$
