Answer:
4) undefined
Step-by-step explanation:
When graphing x=3, you'll find that it is a vertical line, that intersects the x axis at 3.
Slope is rise over run.
Our line is rising infinitely for every 0 runs.
So it would pretty much be infinitely/0
Since you can't divide a number by 0, we consider the slope of a vertical line, undefined.
