How to prevent rolling back when starting on a slope with an automatic transmission?

[WalkerRose]

Before starting, be sure to firmly pull the handbrake. Use your right foot to firmly press the brake pedal when starting the car, and only start the car when everything is ready. When preparing to start the car, first press the brake, shift to N gear, and then ignite. Shift from N gear to D gear, release the handbrake, and lift your foot off the brake. Once everything is ready, you can release the brake, while simultaneously moving your right foot to the accelerator pedal, gradually applying throttle, and slowly releasing the handbrake with your right hand.
