Explanation:

Step1: Simplify -√9

-√9 = - 3, which is a rational number as it can be written as $\frac{-3}{1}$.

Step2: Analyze -2.8

-2.8 is a rational number since it can be written as $\frac{-28}{10}$.

Step3: Analyze 0

0 is a rational number as it can be written as $\frac{0}{1}$.

Step4: Analyze 2

2 is a rational number as it can be written as $\frac{2}{1}$.

Step5: Analyze √10

√10 is an irrational number because it cannot be written as a fraction $\frac{a}{b}$ where a and b are integers and b≠0.

Answer:

√10
