ERROR ANALYSIS:Two students made stem-and-leaf plots for the following data: 530, 545, 550, 555,560, 570. Which is incorrect? Explain the error. A; there is no stem for 56.

B; there are no leaves for 55.

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.
