9-115.

Copy the following table on your paper. .

 $x$ $y$ $4$ $\frac { 1 } { 2 }$ $–2$ $–1$ $7$ $–11$ $1$ $–3$ $–1$
1. Complete the table.

Use pattern between different coordinates to help you fill in the table.

2. Write the rule.

See problem 9-82 for help in finding the rule of the table.

Rule: $y = −2x − 3$
What would the slope be based on this equation?

3. What is the slope?

It might be easier to use the points $(−2, 1)$ and $(−1, −1)$ to find the slope.
