How to do a master reset on LG Xenon using only hardware buttons, the touchscreen is unresponsive to touch.?

Out of absolutely nowhere, my touchscreen on my LG Xenon stopped responding to touch no matter what, and I'm thinking maybe if I get it a master reset using only hardware buttons than I can get it to reset and hopefully become responsive again.

you can either take the battery out for like 5-10 mins...or you can go to the store where you bought the phone, and they will fix it free of charge...
