Which equation represents a parabola opening to the right with a vertex at the origin and a focus at (4, 0)? a: x=1/8 y^2

b: 1/16 y^2

c: -1/8 y^2

d:-1/15 y^2

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.
