To determine which ordered pair is a solution to the equation \(3x - 8 = -4y\), we will substitute the values of \(x\) and \(y\) from each ordered pair into the equation and check if the equation holds true.

  1. For the pair \((-1, 1)\): \[ 3(-1) - 8 = -4(1) \ -3 - 8 = -4 \ -11 \neq -4 \text{ (not a solution)} \]

  2. For the pair \((1, 1)\): \[ 3(1) - 8 = -4(1) \ 3 - 8 = -4 \ -5 \neq -4 \text{ (not a solution)} \]

  3. For the pair \((0, -2)\): \[ 3(0) - 8 = -4(-2) \ 0 - 8 = 8 \ -8 \neq 8 \text{ (not a solution)} \]

  4. For the pair \((0, 2)\): \[ 3(0) - 8 = -4(2) \ 0 - 8 = -8 \ -8 = -8 \text{ (this is a solution)} \]

The only ordered pair that is a solution to the equation \(3x - 8 = -4y\) is \((0, 2)\).
