What is the equation of the line parallel to the x-axis and four units above the x-axis?

Answer Choices

Answer

A line that is parallel to the x-axis and four units above the x-axis is the vertical translation of the x-axis four units upward. Since the x-axis is a horizontal line and has equation y = 0, it follows that the line parallel to the x-axis and four units above the x-axis has equation y = 4.
