This is the graph of f(x) - 4 . What is the horizontal asymptote of f(x)?
O A. The x-axis
OB. The line x = -1
C. The line y = -1
O D. The y-axis

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
