Answer: C, E, F
Step-by-step explanation:
- Plug in the "x" and "y" values from the ordered pairs into the equation.
- For A: 3 =
→ 3 ≠ 1 → A is eliminated.
- For B: 5 =
→ 5 ≠
→ B is eliminated.
- For C: 2 =
→ 2 = 2 → C satisfies the equation.
- For D: 10 =
→ 10 ≠
→ D is eliminated.
- For E: -1 =
→ -1 = -1 → E satisfies the equation.
- For F: 3 =
→ 3 = 3 → F satisfies the equation.
- Therefore, C, E, and F are the answers.
