6-110.

Multiple Choice: Which equation below could represent a tile pattern that grows by $3$ and has $9$ tiles in Figure 2?

1. $3x + y = 3$

1. $−3x + y = 9$

1. $−3x + y = 3$

1. $2x + 3y = 9$

Work backwards from Figure 2 to find the starting value of tiles at Figure 0, then write the rule and match your answer.

(c) $−3x + y = 3$
