Answer

No slope, or an undefined slope, means that the slope is infinitely steep.

Work Step by Step

We know that a 0 slope means that m=0, while an undefined slope means that the line is vertical, which makes the slope infinite. Since an undefined slope cannot be expressed as a real number, we know that "no slope" is a synonym for an "undefined slope."
