Me with these exponents!

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.

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.

If f(x) = 4x - 3 and g(x) = x + 4, find (f - g) (x)
