You can inform her that someone elder (maybe your mom / dad) would be at home. That may make her believe that nothing wrong would happen.
convince herif it doesn't work convince your dad
Tell her you are responsible

Just keep asking her about it. It actually took me three years to convince my mom and dad to let me get my bellybutton pierced.
Well, if it's you first time, point out that you've never been to one before and would like to try it out. You could also try to find out what activities you are going to do from the person that is hosting the sleepover and list them out to your parents, to make them realize all the fun you might miss. It took me awhile to convince my parents for a first sleepover also, but now they say "Yes" without even thinking.
sorry but that really depends on your mom....
Have an honest conversation with your mom about your desire to go to the sleepover and assure her that you will be responsible and safe. Offer to provide her with more information about the guy and the sleepover to alleviate any concerns she may have. Respect her decision and be understanding if she says no.
Buy your own
Just ask her for one
Move out.
You can convince your mother by letting her know that you are responsible.
