Solution Steps
To determine whether each ordered pair \((x, y)\) is a solution to the equation \(5x - 8y = -29\), substitute the values of \(x\) and \(y\) from each pair into the equation. If the equation holds true (i.e., both sides are equal), then the pair is a solution; otherwise, it is not.
Step 1: Evaluate the Pair \((-3, 1)\)
Substituting \(x = -3\) and \(y = 1\) into the equation \(5x - 8y\):
\[
5(-3) - 8(1) = -15 - 8 = -23 \neq -29
\]
Thus, \((-3, 1)\) is not a solution.
Step 2: Evaluate the Pair \((0, -4)\)
Substituting \(x = 0\) and \(y = -4\) into the equation:
\[
5(0) - 8(-4) = 0 + 32 = 32 \neq -29
\]
Thus, \((0, -4)\) is not a solution.
Step 3: Evaluate the Pair \((-9, -2)\)
Substituting \(x = -9\) and \(y = -2\) into the equation:
\[
5(-9) - 8(-2) = -45 + 16 = -29
\]
Thus, \((-9, -2)\) is a solution.
Step 4: Evaluate the Pair \((6, 5)\)
Substituting \(x = 6\) and \(y = 5\) into the equation:
\[
5(6) - 8(5) = 30 - 40 = -10 \neq -29
\]
Thus, \((6, 5)\) is not a solution.
Final Answer
The only ordered pair that is a solution to the equation \(5x - 8y = -29\) is \((-9, -2)\). Therefore, the answer is:
\[
\boxed{(-9, -2)}
\]
