General equation is

Where (h,k) is the center
From the given equation h=0 and k=0
So center is (0,0)
compare the given equation with general equation
b^2 = 4 so b= 2
a^2 = 49 so a = 7


Vertices are (h, k+a) and (h, k-a)
We know h=0 , k=0 and a= 7
Vertices are (0,-7) and (0,7)
Foci are (h, k+c) and (h,k-c)
We know h=0 , k=0 and c=

Foci are (0,-
) and (0,
