y^7

Step-by-step explanation:

If we want to simplify the expression $y^9 \cdot y^{-2}$ , we have to note that exponent rules state that $x^a \cdot x^b = x^{a+b}$ .

This means that if we add the exponents, that will be what we raise y to the power of.

9 + -2 = 9-2 = 7

So y^7 .

Hope this helped!
