Final Answer: $undefined$

Steps

Step 1 ：Given that $x = - 9$ and $y = - 8$ , we are to evaluate the expression $\frac{7 - 4 x}{y + 8}$

Step 2 ：Substitute $x = - 9$ and $y = - 8$ into the expression to get $\frac{7 - 4 (- 9)}{- 8 + 8}$

Step 3 ：Simplify the expression to get $\frac{7 + 36}{0}$

Step 4 ：However, division by zero is undefined in mathematics. Therefore, the expression is undefined.

Step 5 ：Final Answer: $undefined$
