Yes, the slope can be a fraction; and can be less than one or negative.
The slope can be a fraction.

yes, slope can be fraction. It's like -1, -1/3 , 4/5 , 4 and so on.
Only if it happens to BE a whole number. As you probably know, you can't "convert" a fraction to a whole number, without losing precision. But the slope may well happen to be a whole number, such as 1, 2, 3, -1, etc. (or close enough to a whole number).
Why not? m=4/3 is a perfectly good slope
The equation for slope = rise / run
Steepest line possible dealing with slope is up to, but not including infinity.
It is simply the arctan transformation of the fraction.
Yes
The slope is the rise over the run, like a fraction. Rise is the numerator, run is the denominator. That gives you a fraction. Then just divide if you want a number.
A line must be in 2-dimensional space to have a slope. In 2-d space, each point is identified by an ordered pair of coordinates. The points in the question are not and so it is not possible to answer the question.
The same rules apply but it might help if you turn the fraction into a decimal.
