This is because whether a function has a vertical asymptote (VA) or not is not affected by the numerator. The denominator is where the VA originates when you try to divide by 0. For example, y=x/(x-1) and and y=1/(x-1) BOTH have VAs when the denominator is equal to zero. x-1=0 when x=1, so that's where the VA is, regardless of the numerator.
If there are no coordinates given then you cannot.
Not all rational functions have holes. A rational function is a ratio of two polynomials, and holes occur at points where both the numerator and denominator equal zero, indicating a common factor. If a rational function has no common factors between the numerator and denominator, it will not have any holes, although it may have vertical asymptotes or other features.
No. Vertical lines are not.

They are not. A vertical line is not a function so all linear equations are not functions. And all functions are not linear equations.

It's called a vinculum.

If your computer screen has vertical lines on it sometimes your monitor or graphics card may be dying.

Sometimes but not always.
