Question

Which of the following best describes the slope of the line below ?

Answer 1

we have

The equation of the graphed function is

$y=4$

we know that

The slope of the line parallel to the x-axis is equal to zero and the slope of the line parallel to the y-axis is undefined

In this problem

The line is parallel to the x-axis

so

The slope is equal to zero

Remember that

The formula to calculate the slope is equal to

$m=\frac{y2-y1}{x2-x1}$

In this problem the value of y is constant

so

$m=\frac{4-4}{x2-x1}=0$

therefore

the answer is

Zero

Answer 2

Answer zero, because you must find slope.

5/0= 0 

Good luck =)
