1. Write the expression:  
   $$
   -9\sqrt{y} + 2\sqrt{y}
   $$

2. Notice that both terms contain the common factor $$\sqrt{y}$$.

3. Factor out the common factor:  
   $$
   \sqrt{y}(-9 + 2)
   $$

4. Simplify the expression inside the parentheses:  
   $$
   -9 + 2 = -7
   $$

5. Thus, the simplified expression is:  
   $$
   -7\sqrt{y}
   $$
The simplified expression is $$-7\sqrt{y}$$.
