9-27.

1. Write the rule for the table at right.

See problem 9-58 for help in finding the rule of the table.

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

2. What is the slope?

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

3. What is the $y$-intercept?

 $x$ $4$ $\frac { 1 } { 2 }$ $–2$ $–1$ $7$ $y$ $–11$ $1$ $–3$ $–1$
