bleed the slave first. you can gravity bleed by packing nose up an inline, open the clutch master reservoir and fill it up. then open up the bleeder on the slave an let gravity do it's thing. keep an eye on the fluid and keep the reservoir topped up. Let it flow until you get clear fluid out. then,finally, the last step is to get the last bubbles out of the slave. put the cover back on the master, then put vise grips on the end of the slave push rod, open the bleeder again all the way, and push the push rod into the slave, hold, and close the bleeder, then you can let go of the push rod. you may have to do it a couple times to get the hang of it.
...or, you could just get someone to help.....
