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

Answer:
1. x=17.5
2. x=77
Step-by-step explanation:
1. -x=-3x+35
=2x=35
x=17.5
2. -x/7+8=-3
=-x/7=-11
=-x=-77
x=77
I believe the answer is 6
