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 ✎
3x + y = 3
−3x + y = 9
−3x + y = 3
2x + 3y = 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 (Ax + By = C).
