3-84.

On graph paper, draw Figure 0 and Figure 4 for the pattern below.

 tile $\space \space$ tile $\space \space$ tile $\space \space$ tile $\space \space$

Figure 1

 tile $\space \space$ tile $\space \space$ tile $\space \space$ tile $\space \space$ tile $\space \space$ tile $\space \space$

Figure 2

 tile $\space \space$ tile $\space \space$ tile $\space \space$ tile $\space \space$ tile $\space \space$ tile $\space \space$ tile $\space \space$ tile $\space \space$

Figure 3

1. Represent the number of tiles in each figure with:

• An $x→y$ table.

• An algebraic rule.

• A graph.

Try and find a connection between the figure number and the number of tiles.

2. Without drawing Figure 5, predict where its point would lie on the graph. Justify your prediction.

Use the information found in part (a), and find what $y$ is when $x=5$ on the graph.
