You can put this solution on YOUR website!
x^2 - 5x >= -6
x^2 - 5x + 6 >= 0
(x - 2)(x - 3) >= 0

x is in (-infinity, 2] and [3, infinity)


0........1........2........3........4........5

The solutions by   @CubeyThePenguin  is INCORRECT.

I came to bring you the correct solution.


    x^2 - 5x >= -6   ----------->


    x^2 - 5x + 6 >= 0


    (x-3*(x-2) >= 0


    ANSWER.  The solution set  is  (-oo,2] U [3,oo).


Ignore the post by @Penguine, since his plot is incorrect.
