\newline

Write your answer in simplest form.

\newline

\frac{r - 9}{-r + 6} =

Identify Expression: Identify the expression after substituting $r = 8$ Substitute $8$ for $r$ in $\frac{r - 9}{-r + 6}$ . $\frac{8 - 9}{-8 + 6}$
Substitute and Simplify: Evaluate $8 - 9$ $\newline$ $8 - 9 = -1$ $\newline$ Numerator: $-1$
Evaluate Numerator: Evaluate $-8 + 6$ $-8 + 6 = -2$ Denominator: $-2$
Evaluate Denominator: $-1/(-2)$ $\newline$ Rewrite the fraction in simplest form. $\newline$ Divide both $-1$ and $-2$ by $-1$ to simplify. $\newline$ $-1/(-2) = 1/2$
