To determine which of the numbers listed are irrational, let's evaluate each one:
1. **√9**: The square root of 9 is 3, which is a rational number (it can be expressed as 3/1).
2. **π (pi)**: Pi is an irrational number, which means it cannot be expressed as a fraction of two integers.
3. **5/2**: This is a rational number because it can be expressed as a fraction (5 divided by 2).
4. **-1**: This is also a rational number, as it can be expressed as -1/1.
So, the only irrational number in the provided list is **π (pi)**.
