100x%5E2%2B121y%5E2=12100
100x%5E2%2F12100%2B121y%5E2%2F12100=12100%2F12100
x%5E2%2F121%2By%5E2%2F100=1

x%5E2%2F11%5E2%2By%5E2%2F10%5E2=1....so, it's an ellipse with center at origin
(h,k)=(0,0)
semi-major axis length: a=11
semi-minor axis length:b=10

x-intercepts at (-11,0) and (11,0)
y-intercepts at (0,-10) and (0,10)
