Question

What is the slope of a line that is parallel to the x-axis? 0 1 undefined

Answer 1

its 0 because the slope would be one if it was a positive line and itd go up and across one unitl and it is undefined if it is parallel to the y axis

Answer 2

The slope is 0.

Explanation:

In the plane, we can write all the lines using the following equation :

`y=ax^(2)+b`

Where ''a'' and ''b'' are real numbers and ''a'' is the slope of the line.

If
`a=0` we will have the following lines :

`a=0` ⇒
`y=(0)x^(2)+b\\y=b`

All the lines with the form
`y=b` are parallel to the x-axis and intersect the y-axis in the point
`(0,b)`.

The slopes of all this lines is equal to 0 given that
`a=0`
