For this case, we have the following equation of the second degree:

If we divide between 2 on both sides of the equation, we will have:

Where:

The solutions will come from:

Substituting:

So, we have:

Answer:

Option A
Option E
Answer:
B
In the equation y=mx+b m is the slope of the line.
Therefore the coefficient in each of these equations is the slope.
A line with a perpendicular slope must have the inverse opposite of the actual line. For example if a line has a slope of 5, a perpendicular line to that line must have a slope of -1/5. If a line has a slope of 10, the perpendicular line has a slope of -1/10. If a line has a slope of 2 then the inverse opposite is -1/2 and that is the slope of the perpendicular line.
B is the only answer with the correct slope so B is the answer.

Answer:
AB = 9
Step-by-step explanation:
Given that line, l is a perpendicular bisector of line segment AC. It intersects line segment AC at point B.
So, we can conclude that AB = BC ............ (1)
Also given that the length of line segment BC is 9.
Now, from equation (1) we can say that, AB = 9.
Therefore, the length of segment AB is 9. (Answer)
