contrary to what others have said, you always keep your weight centered, Don't lean back, keep your approach to the jump smooth and a constant speed.
Most of your trajectory depends on your throttle work just before you leave the ramp, never back off the throttle, a small braaaap before you leave the ramp will get the front wheel up and going where it needs to, not doing this will have you landing on your front wheel or possibly going over the bars.
As the others have said, don't go big, start small and try to get your throttle work down pat and landing consistently on 2 wheels..
good luck... we expect an update on your progress...
