Question 726052
Write an equation of an ellipse in standard form with the center at the origin and with the given characteristics. 
vertex at (–3, 0) and co-vertex at (0, 2)
***
Given ellipse has a horizontal major axis.
Its standard form of equation: {{{(x-h)^2/a^2+(y-k)^2/b^2=1}}}, a>b, (h,k)=(x,y) coordinates of center
For given ellipse:
center:(0,0)
a=3
a^2=9
b=2
b^2=4
Equation of given ellipse:
{{{x^2/9+y^2/4=1}}}
