Move the leading negative in $- \frac{1}{3}$ into the numerator.

$f (9) = \frac{- 1}{3} \cdot 9 + 1$

Factor $3$ out of $9$ .

$f (9) = \frac{- 1}{3} \cdot (3 (3)) + 1$

Cancel the common factor.

$f (9) = \frac{- 1}{3} \cdot (3 \cdot 3) + 1$

Rewrite the expression.

$f (9) = - 1 \cdot 3 + 1$

Multiply $- 1$ by $3$ .

$f (9) = - 3 + 1$

Add $- 3$ and $1$ .

$f (9) = - 2$
