Answer:
The answer is the option A
The line is horizontal. The slope is
Step-by-step explanation:
we know that
The slope of the line parallel to the x-axis is equal to zero and is called a horizontal line
The slope of the line parallel to the y-axis is undefined and is called a vertical line
In this problem we have
This is a line parallel to the x-axis
therefore
Is a horizontal line with slope equal to zero
