Answer 1

To determine which of the given ordered pairs is part of the relation defined by the equation \( y = -\frac{2}{3}x + 6 \), we can substitute the x-value of each ordered pair into the equation and see if the resulting y-value matches the second number in the pair.

1. **For (3, 4):**

\[
y = -\frac{2}{3}(3) + 6 = -2 + 6 = 4
\]

This pair is valid, as \( y = 4 \).

2. **For (3, 8):**

\[
y = -\frac{2}{3}(3) + 6 = -2 + 6 = 4
\]

This pair is not valid, as \( y \neq 8 \).

3. **For (0, -\frac{2}{3}):**

\[
y = -\frac{2}{3}(0) + 6 = 0 + 6 = 6
\]

This pair is not valid, as \( y \neq -\frac{2}{3} \).

4. **For (1, 4):**

\[
y = -\frac{2}{3}(1) + 6 = -\frac{2}{3} + 6 = \frac{-2 + 18}{3} = \frac{16}{3}
\]

This pair is not valid, as \( y \neq 4 \).

The only ordered pair that satisfies the equation is **(3, 4)**.
