Answer: 
Step-by-step explanation:
For it to bisect the segment, we need to find the midpoint.
The midpoint is 
.
Now, for it to be perpendicular, we need to use the fact that perpendicular lines have slopes that are negative reciprocals of each other.
The slope of the given segment is 
, so the slope of the perpendicular bisector is 6.
Thus, the equation of the line in point-slope form is
