Basketball players.....I need help shooting with proper form?

My basketball coach has me stand around 2 or 3 ft. away from the basket. I have to shoot with my shooting hand and put backspin on the shot. If u need to use your weak hand to guide the ball but put your hand down before you shoot. Remember to flick your wrist towards the basket and keep your elbow in and when you feel like your shot is off go to the free throw line
