Zero is pretty well defined. Division by zero is undefined.
A line with an undefined slope is a vertical line. A line with a slope of zero is a horizontal line. If you use the formula for slope m = (y2-y1) divided by (x2-x1)... For an undefined slope you will get zero in the denominator, which you cannot have because you cannot divide by zero. For a slope equal to zero, you will get a zero in the numerator. Zero divided by any non-zero denominator, will give you a slope of zero.
Undefined.

Zero to any power is zero; any non-zero number to the power zero is one. Thus, zero to the power zero is sort of contradictory.

-9 over anything but zero is a fraction. Division by zero is undefined.

The rule says no dividing by zero. So it is undefined.
Division by zero is undefined.
8 divided by 0 is undefined

infinity? Infinity over zero is undefined, or complex infinity depending on numbers you are including in your number system.
A quotient is undefined if the divisor is zero.
Because slope is defined as change in y over change in x, for a vertical line your change in x is zero. Dividing by zero gives an undefined answer.
