You can put this solution on YOUR website! Find the ellipse equation with ends of minor axis at (-1,2) and (-1,-4) and focus at (1,-1)
Given data shows ellipse has a horizontal major axis.
Its standard form of equation: ,a>b, (h,k)=cooordinates of center
y-coordinate of center=-1 (midpoInt of 2 and -4 on the minor axis)
x-coordinate of center=-1
center: (-1,-1)
c=2
c^2=4
b=3
b^2=9
c^2=a^2-b^2
a^2=c^2+b^2=4+9=13
Equation of given ellipse:
