You can put this solution on YOUR website! Find equation of ellipse having vertices (10,0) and (-10,0) and minor axis (0,9) and (0,-9)
Data shows given ellipse has a horizontal major axis:
Its standard form:  , a>b, (h,k)=(x,y) coordinates of center
For given ellipse:
center: (0,0)
length of horizontal major axis=20=2a
a=10
a^2=100
length of minor axis=18=2b
b=9
b^2=81
Equation of given ellipse:
