To determine which inequalities the point (2, 2) is a solution for, we can substitute \(x = 2\) and \(y = 2\) into each inequality.
1. **Inequality:** \(y < -2x + 1\)
- Substitute \(x = 2\) and \(y = 2\):
- \(2 < -2(2) + 1\)
- \(2 < -4 + 1\)
- \(2 < -3\) (FALSE)
2. **Inequality:** \(y \geq 3x - 2\)
- Substitute \(x = 2\) and \(y = 2\):
- \(2 \geq 3(2) - 2\)
- \(2 \geq 6 - 2\)
- \(2 \geq 4\) (FALSE)
3. **Inequality:** \(y > x - 1\)
- Substitute \(x = 2\) and \(y = 2\):
- \(2 > 2 - 1\)
- \(2 > 1\) (TRUE)
So, the only inequality that (2, 2) satisfies is \(y > x - 1\).
**Final Answer:**
- \(y > x - 1\) is the only inequality where (2, 2) is a solution.
