What is the fourth persons time and, with these numbers it should be anything lower than 9.75.
The perpendicular bisector of the segment passes through the midpoint of this segment. Thus, we will initially find the midpoint P:

Now, we will calculate the slope of the segment support line (r). After this, we will use the fact that the perpendicular bisector (p) is perpendicular to r:


We can calculate the equation of
p by using its slope and its point P:
Answer:
5.) b = -2/5 (or -0.4 in decimal form)
6.) 20.5
