To answer the question above, I'll make a step by step procedure below.
9x2/144 + 16y2/144 = 144/144
Then Simplify,
x2/16 + y2/9 = 1
The major axis is the x-axis because the largest denominator is under the x2 term.
The coordinates of the vertices are as follows ...
(±a,0)
(0,±b)
a2 =1 6→a = 4
b2 = 4→b = 2
So the answer to your question are
(±4,0)
(0,±2)
i hope I helped you with your problem
