Question

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

Answer 1

Answer:

The slope is 0.

Step-by-step 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 $a=0$

Answer 2

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
