a. 0 b. 5/6

c. 6 d. undefined

This is for extra points, that I really need in my algebra II class =).

Well, the line x = 6 looks like a vertical line ( up and down ) ... going through the point (6, 0) on the x-axis.

Vertical lines have an undefined slope.

So,

Go back to your basic definition:

We can get two points on this line: say (6, 1) and (6, 2).

Since we can't divide by 0, this slope is undefined.

Comment:

You have now posted several extra credit questions. I have noticed that many of the solutions depend directly on basic definitions. If the definitions are giving you problems I would strongly recommend you review these with your teacher to make sure you understand them. Otherwise, as I think Aftershock mentioned, none of this will help you.
