Each floor of a hotel as r rooms. on 8 floors, there are a total of 256 rooms. write an equation to represent this situation

How do you answer this question? (step by step)

The table respent two linear functions the equation respented by the first tables is given

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.
