Vertex form is

where (h,k) is the vertex.
We can see that the vertex of the graph is at (2,0), and that the graph opens downwards, but does not look stretched at all.
Therefore,
a = -1
h = 2
k = 0
and our vertex form equation is

which is answer A
Answer:
B
Step-by-step explanation:
If you graph y^2/361 + x^2/169=1 you will get the same graph depicted in the equation.
Answer:
1 is the answer
Step-by-step explanation:
bc the first number represent x and the second y
(x,y)
