chain rule is important here
I'll show the steps partially
now evaluate for (-2,2)
x=-2 and y=2
that's it, simplest form

First we must change these numbers to improper fractions:
So then we set it up:
÷
When we divide fractions like this, we must flip the second fraction and change the sign from division to multiplication like so:
Then we solve:
Then if we divide the numerator and the denominator by 9, we get:
or, in mixed-number form,
.
