How do you write the equation of an ellipse with vertices at (-5,1) and (-1,1) and co-vertices at (-3,2) and (-3,0)?
Center (h,k) lies on the x-axis .
so midpoint of vertices is the center.
a=length of semi-major axis
b=length of semi-minor axis
Equation of ellipse:
Plug the values of a,b and (h,k)
