ZERO pitch
All drains slope 1/4 inch per foot, minimum. Too much slope,though, can mean pulling water out of the trap or goose neck on a toilet.
The minimum slope required for roof drainage to ensure proper water flow is typically 1/4 inch per foot.
24 and 719 is not enough information to define a slope. For 2-dimensional space two ordered pairs are the minimum required.
The minimum slope shall be 1% to 2%.
To slope a floor to a drain, first determine the drain's location and the required slope, typically 1-2% (1/8 to 1/4 inch per foot). Mark reference lines on the floor using a level or chalk line to ensure a consistent slope towards the drain. Then, adjust the subfloor or pour a sloped layer of concrete or mortar, ensuring that the high point is away from the drain and gradually lowers toward it. Finally, finish the surface to ensure proper drainage and a smooth transition.
Generally 1 in 300 is sufficient for parking space, but it can be variable depending upon the location/conditions of site

Fall off is critical. If too shallow it will not fall away and smell - if too steep it will fall away too quickly and can be forced back up. The slope from the entry point to the toilet is ratio 1:50 - for every 50cm it moves along the wall the floor will need to be raised by 1cm. If the WC is within 2 mtrs of the window it can usually go under the floor depending on which was the joists are laying. Wcs should be no more that 6m from the soil stack.
If you are asking about the correct gradient. It is 1:40 (meters)
An island slope is analogous to a continental slope, but it is attached to an oceanic island (volcano) rather than attached to a continent. In simple terms, it is that portion of the sea floor that slopes from an island's shallows down to the deep ocean floor.
