To calculate the inverse of y = -x,
you have to interchange the variables and solve for y.
Therefore, we have to solve for y in the equation x = -y
y = -x
The inverse is itself.

Look at it graphically. The inverse of the function it its mirror image wrt to the diagonal line y=x.
The line y=-x forms a big 'X' with the line y=x. If you take that big 'X' and rotate it around the '/' line, you'll see that the '\' line will just rotate back onto itself and the result is the same 'X' image.

It is its own inverse

f(x) = - x
has inverse
f^(-1)(x) = -x
because f(f(x) = f(-x) = x
