1995 Honda Passport Clutch Fluid

The clutch resevor is leaking fluid, it has been doing this for awhile now, but we have just been making sure that we watch the fluid level, now it will not hold any fluid for more that 2 to 3 hours. I was trying to find the slave cylinder, but can not find it. I was told that it should be by the passenger tire on the front end, but still could not see it. Could you tell me where it is and it this sounds like the slave cylinder or maybe the something else.
