Try to do as little as possible of a slope, so you won't feel it but so it has a slope

Because of snow 8/12 .
Some slopes for airport underground baggage ramps can be as steep as 90 degrees. The slope is necessary to both save space and facilitate the travel of the baggage to the underground area to be sorted.

A 1/8th inch per foot slope is sufficient enough to properly drain any precipitation. Other than for the purposes of drainage, a slope on a driveway is unnecessary unless it is to deal w/ changes in elevation.
Yes
underground mining is done when the rocks, minerals of gemstones are too far underground to get out with surface mining some kinds of underground mining are Borehole Mining Drift Mining Hard Rock Mining Shaft Mining Slope Mining
1/8" per foot
no, a brick slide down on the slope of concrete the slowest
Take the slab out and pour a new one with the right slope. Rent a concrete saw and cut a few grooves in it making the groove deeper away from the house. This will let the water drain off of the slap and away from the house. If the slab is separate from the house, you might be able to mud jack it at the house and raise it enough to slop it away from the house. Mud jacking is not terribly expensive.
A 1/4" per foot is standard, therefore in twenty feet the furthest point would be 5" below the high point. You can make it flatter (3 or 4 inch drop) but it would require greater perfection in concrete placement, perhaps beyond reason.
miners take machines for underground miningthey use three types of mines : lope, slope,and shaftthis is very helpful info
