    Swap x and y to go from y = -x-1 to x = -y-1

    I did and I got the same as before I did the inverse... is that correct?

    that is correct, the reason why is because y = -x-1 is perpendicular to y = x

    if you reflect y = -x-1 over the line y = x, you'll see that the line y = -x-1 will reflect over itself (ie it's symmetrical about the line y = x)
