# Is the slope of the #y# axis infinity?

##### 2 Answers

When we derive this result, we take the slope of one line as

hence their product becomes -1 .

For your case the slopes are

Also the product of a number tending to infinity and a number tending to zero is not fixed and it depends upon the question .

No. The slope of the

#### Explanation:

The slope of the

The slope of the

You can try hard to make it "infinity", but what "infinity" do you mean?

For example an standard calculus definition would give you:

#lim_(x->0+) 1/x = +oo#

#lim_(x->0-) 1/x = -oo#

So using these kind of definitions, you would not know if the slope of the

Note that

For example:

What is

#oo - oo# ?What is

#0 * oo# ?

Both are indeterminate.

The property that the product of the slopes of a pair of perpendicular lines is

Intuitively, the slope of the

Instead of the standard calculus objects
