My opinion of your situation is this: It would depend on several things including what the $1 VP is (although I'm now seeing that at least VPFree2.com says that there is $1 9/6 Jacks Or Better VP there). I'm saying this because that may or may not be the better route to go if it is allowed to be played on Video Poker (some Freeplay may be restricted on what you can play it on -- this differs from casino to casino). I would say that return-wise, I think that you might be more likely better off playing the VP rather than the Slot machine if those are your only choices. Although it could also depend on how accurate your VP play is.
If you played $100 through a $1 VP machine at $5 per hand (although I do see that it is also available at the $0.50 denomination), that would only be 20 or 40 hands of play (remember that all that has to be done with Freeplay is for it to be played through exactly one time). That's a very short amount and you might not end up with many good hands (although I think that it still would be more likely be better than a Slot Machine).
But, another option, if available, would be to play it through Video Blackjack. Now although it is not normally a good thing to play Video Blackjack if Blackjack is paying Even Money (1 To 1 -- although the machine may actually say "Blackjack Pays 2 For 1" -- but 2 For 1 is 1 To 1), it has a lower Variance (Volatility) than VP or Slots but it could be returning about maybe 96-97% (depending on the rules that are or are not offered) in the short and long run whereas with Video Poker in the Short Run, it could return a lot less than that. This may very well be the best way for you to extract as much of this potential $200 as possible.
What I mean by this is that for example, in VP, 4-Of-A-Kinds comprise about 6% of the game's entire return and so if your session doesn't have one, even with 9/6 Jacks (and here 4-Of-A-Kinds average about 1 in 423 hands), that would put the return at the very least down to about 93%, plus you also can pretty likely also remove the Royal Flush and Straight Flush from that pay which will lower the return about an additional 2.5% (which would lower the return down to about 90.5%).
But if you are forced to use it on a Slot Machine only, your best move might be to play every single line, but for one coin on each line.
And if you have the 2015 American Casino Guide, also check the listing of Slot Machine returns that the machine manufacturers offer the casinos for the specific games and maybe look for the games that list the highest possible range of returns (although that is still no guarantee that the casino will actually offer the best returns).
