Determine the graph foci and asymptote equation of x^2/4-y^2=1

Answer:
B)
Foci: ((sqrt5),0),((-sqrt5),0)
Asymptotes: y=((1/2)x), y=((-1/2)x)
Step-by-step explanation:
Same rule with x before y as I mentioned in the other problem to identify the graph.
Answer: A. (THE FIRST GRAPH)
here's ss so you can see that it's correct + the top two graphs that were cut off in the question :)
