Which statements are true? Select three options. 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.
