They don't have the same x-coordinates or the same y-coordinates so it is neither.
for all positive integers (like n = 1, 2 or 5) the conjecture holds true but not for negative values like if n = -3 then the result will not become positive, because:

which is not positive.
Answer:
B
Step-by-step explanation:
I think I'm not sure. Please tell me if I'm wrong.
gen. Equation is...
x²/a² - y²/b² =1
a=length from origin to vertex
a=2
b=length from origin to focus
b=9
so equation is
x²/2² - y²/9² =1
-> (x²/4) - (y² /81) =1
Hope it helps...
