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:
1/8
Step-by-step explanation:
The decimal answer of -11/9 would be -1.22 with the .22 repeated.
Remember the notation..
When you have a triangle called ABD, the angles may be called in theses equivalent ways>
angle A is equivalent to ∠ DAB
angle B is equivalent to ∠ ABD
angle D is equivalen to ∠ BDA
Then given that the two triangles are congruent, you can say an
angle B = angle F = ∠ EFC
So the answer is the last option of the list.
Four times d to the third minus ten
