Complete the table.

 $x$ $-5$ $1$ $3$ $0$ $8$ $-2$ $-1$ $y$ $7$ $2$ $4$
1. Find the rule.

Do you see any patterns?
Notice the difference in the $y$-value from $x = 0$ to $x=-2$.

Also notice that as the $x$-value decreases, the $y$-value increases, and vice versa.

$y=-x+2$

2. What is the slope?

$\text{Slope} = \frac{\text{rise}}{\text{run}}$

$-1$
