Answer:
y=4x+47
I wanted to wait for the person who originally said the answer but it's been a while and I kinda want the points. Sorry
This is how i worked it out.
Good Luck
Answer: 
Step by step:

(Used a table of common angles)
Answer:
They would never intersect because they are parallel lines. You can tell they are parallel lines because they have the same slope and they have a different y-intercept. However, this doesn't mean that there was no solutions, there were, thats how i was able to tell what their slopes and y-intercepts were. So if there is an answer that you can choose from that explains that they won't intersect because they are parallel then that is the correct answer. It may be C, but I would see if there is another option.
What exactly are we solving?? the rest of the angles or the perimeter?
