If a baby uses 15 diapers in 2 days how many diapers will the baby use in a year

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.

Wich statement could be used to explain why the function h(x)= x^3 has an inverse relation that is also a function
