Answer:
D is correct. 
Step-by-step explanation:
We are given the root of the equation

If we are given solution of the equation then find equation using formula.
If a and b are the solution of equation then equation would be (x-a)(x-b)=0
Here, 
Equation form would be 
Now we simplify the above equation to get correct option.


So, D is correct. 
The midpoint is (0.5, 1.5)
you use (x2-x1)/2 and you add that number to x1 got x midpoint
and is the same way to find y
Yes, because there is a corresponding amount of teachers per student.
