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 see if both sides are equal.
1. For the ordered pair \((0, -2)\):
\[
3(0) - 8 = -4(-2) \quad \Rightarrow \quad -8 = 8 \quad (\text{False})
\]
2. For the ordered pair \((-1, 1)\):
\[
3(-1) - 8 = -4(1) \quad \Rightarrow \quad -3 - 8 = -4 \quad \Rightarrow \quad -11 = -4 \quad (\text{False})
\]
3. For the ordered pair \((0, 2)\):
\[
3(0) - 8 = -4(2) \quad \Rightarrow \quad -8 = -8 \quad (\text{True})
\]
4. For the ordered pair \((1, 1)\):
\[
3(1) - 8 = -4(1) \quad \Rightarrow \quad 3 - 8 = -4 \quad \Rightarrow \quad -5 = -4 \quad (\text{False})
\]
The only ordered pair that satisfies the equation \(3x - 8 = -4y\) is \((0, 2)\).
1. For the ordered pair \((0, -2)\):
\[
3(0) - 8 = -4(-2) \quad \Rightarrow \quad -8 = 8 \quad (\text{False})

\[
3(-1) - 8 = -4(1) \quad \Rightarrow \quad -3 - 8 = -4 \quad \Rightarrow \quad -11 = -4 \quad (\text{False})

To determine which of the given ordered pairs is a solution for the equation \(1.5x - 2y = 8\), we will substitute the values of \(x\) and \(y\) from each ordered pair into the equation:
1. For Fiona's ordered pair \((4, 7)\):
\[
1.5(4) - 2(7) = 6 - 14 = -8 \quad (\text{Not equal to } 8, \text{ so False})
\]
2. For Mary's ordered pair \((4, -7)\):
\[
1.5(4) - 2(-7) = 6 + 14 = 20 \quad (\text{Not equal to } 8, \text{ so False})
\]
3. For Peter's ordered pair \((-4, 7)\):
\[
1.5(-4) - 2(7) = -6 - 14 = -20 \quad (\text{Not equal to } 8, \text{ so False})
\]
4. For Sam's ordered pair \((-4, -7)\):
\[
1.5(-4) - 2(-7) = -6 + 14 = 8 \quad (\text{Equal to } 8, \text{ so True})
\]
Thus, the correct solution is Sam's ordered pair \((-4, -7)\).
1. For Fiona's ordered pair \((4, 7)\):
\[
1.5(4) - 2(7) = 6 - 14 = -8 \quad (\text{Not equal to } 8, \text{ so False})
\]
2. For Mary's ordered pair \((4, -7)\):
\[
1.5(4) - 2(-7) = 6 + 14 = 20 \quad (\text{Not equal to } 8, \text{ so False})
\]
3. For Peter's ordered pair \((-4, 7)\):
\[
1.5(-4) - 2(7) = -6 - 14 = -20 \quad (\text{Not equal to } 8, \text{ so False})

4. For Sam's ordered pair \((-4, -7)\):
\[
1.5(-4) - 2(-7) = -6 + 14 = 8 \quad (\text{Equal to } 8, \text{ so True})
\]
Thus, the correct solution is Sam's ordered pair \((-4, -7)\).
