Identify the line.  Does the x-component of points on the line change?  Do the y-components change?  Consider the formula for the slope of a line.  What would you have in the denominator if the x-coordinate doesn't change?  What does that tell you about the slope of the given line?

mathmale · Answer

Hints:  What would be your response if you were told that the slope of this line were 0/5?
What if you were told that it were 5/0?

Explain.

See if you can finish these sentences:

The slope of a horizontal line is ___________

The slope of a vertical line is  ___________________

That's right; the x-comp doesn't change.   Therefore, (new x value) - (old x value) = ??

anonymous · Answer

the slope of a horizontal like is 0?

mathmale · Answer

Right.  Now, how about answering the other question?

mathmale · Answer

Hint:  x doesn't change!

anonymous · Answer

the slope of a vertical line has undefined slope because all points on the line have the same x-coordinate.

anonymous · Answer

so 0

mathmale · Answer

And so we'd have division by zero if we tried to divide the rise by the run.
No, not zero.  Think:  "division by 0 is ......   ??"

anonymous · Answer

is 0

anonymous · Answer

please help me on my question. @mathmale

mathmale · Answer

Sorry, but div. by zero does not produce a result of zero.  Try again.

anonymous · Answer

ok

mathmale · Answer

One of the famous sayings of Algebra (and also of arithmetic) is:  "Division by zero is ____________________ ."

anonymous · Answer

its unidentified

mathmale · Answer

undefined.

mathmale · Answer

Can't divide by zero, period.  Thus, div. by zero is undefined.
