Leaking Shut-Off Valve on Toilet

I need to replace the shut-off valve on my toilet.
The current one has a flex-hose (if that matters)....
I can't tell if the current shut-off valve was sweated on or
screwed on; consequently, I can't tell how to remove the current valve
and replace it.

Any suggestions on how I can determine how to remove the current valve?
I thought about trying to turn the valve with a wrench (the obvious!), but I'm concerned that if it was sweated on, I could end up w/ a bigger mess!

If you think it may be sweat on then I am assuming it must be a copper supply line. If it is copper and sweat on you should be able to see solder where the valve meets the pipe. It is all but impossible to get all the solder off. If it is copper and screwed on you will be able to see the copper male adapter where it was sweat onto the pipe. You would also see two hex ends, one from the adapter and one for the valve.
One other possibility is that it is a compression valve. They are set on the pipe and when the ring at the bottom of the valve is turned, the compression ring tightens the valve onto the pipe. In this case, you will only see one hex surface. Good luck.

As you can see one will have a nut that connects to pipe out wall, the other you will not see this nut.
