Answer:
The system of equations is

Step-by-step explanation:
Let
x------> the number of videos of new releases
y-----> the number of classics videos
we know that
------> equation A
------> equation B
Using a graphing tool
Solve the system of equations
Remember that the solution of the system of equations is the intersection point both graphs
The intersection point is 
see the attached figure
therefore
the number of videos of new releases is 
the number of classics videos is 
The lines are proven to be parallel so that executes the two perpendicular choices, so I'm assuming it is 'The lines are parallel because the slopes are the same'...
The given equation of parabola is

Which can also be written as

Here vertex (h,k) is (1,2)
And value of a is

Formula of focus is

Substituting the values of h,k and a, we will get

Therefore the correct option is the last option .
