Question

Any line with a slope of zero is parallel to the
O y-axis
O x-axis
O line y = x

Answer 1

Answer:

  x-axis

Step-by-step explanation:

A line with a slope of zero has the same y-value everywhere, so is parallel to the line y=0, the x-axis.

Answer 2

Answer:

x- axis

Step-by-step explanation:

We  are given that any line whose slope is zero.

We have to find the line with a slope  of zero is parallel to which axis.

We know that when any line is parallel to x- axis

It means y does not change with

Therefore, $\frac{dy}{dx}=0$

Slope of a line which is parallel to x- axis is zero because y does not vary with x.

But when a line parallel to y - axis then slope of that line is undefined.

When line y=x

Then , $\frac{dy}{dx}=1\neq 0$

Hence, any line with slope of zero is parallel to the x- axis.

Answer:x- axis.
