A log is 18 m long, correct to the nearest meter. It is to be cut into fence posts which must be 80 cm long, correct to the nearest 10 centimeters.

What is the largest number of fence posts that can possibly be cut from this log?

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.
