To complete the table for the equation \(-x + 9y = 9\), we'll solve for \(y\) in terms of \(x\).

Starting with the equation:

\[ -x + 9y = 9 \]

Rearranging gives:

\[ 9y = x + 9 \]

Now, dividing both sides by 9:

\[ y = \frac{x + 9}{9} = \frac{x}{9} + 1 \]

Now we can calculate \(y\) for each given value of \(x\):

  1. For \(x = 9\): \[ y = \frac{9}{9} + 1 = 1 + 1 = 2 \]

  2. For \(x = 18\): \[ y = \frac{18}{9} + 1 = 2 + 1 = 3 \]

  3. For \(x = 27\): \[ y = \frac{27}{9} + 1 = 3 + 1 = 4 \]

  4. For \(x = 36\): \[ y = \frac{36}{9} + 1 = 4 + 1 = 5 \]

  5. For \(x = 45\): \[ y = \frac{45}{9} + 1 = 5 + 1 = 6 \]

Now, we can fill in the table:

\[ \begin{array}{|c|c|} \hline x & y \ \hline 9 & 2 \ 18 & 3 \ 27 & 4 \ 36 & 5 \ 45 & 6 \ \hline \end{array} \]

This completes the table with the corresponding values of \(y\) for each \(x\).
