9^-1 9^1/2

Any number to the power of a negative number must be flipped to its recipical. Hence it would be 1 ninth or 1/9 x 9 to the power of one half.
anything powered to one half is a square root. That being said your expression would be 1/9 × the square root of 9.
9 is a perfect square to it would be three
1/9 × 3/1 is 1/3 when cross canceled. your answer is 1/3. Hoped that helped.

Y=-2x-6 is the answer
