Find the slope of the line

Find the total area for the regular pyramid ( follow the answer set up in the picture)

What is the area of mnp? 40 m2 60 m2 68 m2 127.5 m2

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.
