6-141.

**Multiple Choice: Which equation below could represent a tile pattern that grows by adding three tiles and has nine tiles in Figure 2? Homework Help ✎**3

*x*+*y*= 3−3

*x*+*y*= 9−3

*x*+*y*= 32

*x*+ 3*y*= 9

Growth is the rate of change or the slope, in slope intercept form (*y* = *mx* + *b*) what variable represents the growth?

Knowing figure 2 has nine tiles, how can you use the growth to find the number of tiles in figure number 0 (starting figure)?

Write the equation in slope intercept form, then rearrange to Standard form (A*x* + B*y* = C).
