Please help! I need the surface area for both. Absurd answer are not tolerated. Thanks if you help!

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.

What value is a discontinuity of x squared plus 8 x plus 4, all over x squared minus x minus 6?
