You can put this solution on YOUR website! find the equation of the ellipse that has its foci at (-1,2) and (-5,2) and a=3
***
Given data shows ellipse has a horizontal major axis.
Its standard form of equation: , a>b, (h,k)=coordinates of center
x-coordinate of center=-3
y-coordinate of center=2
center: (-3,2)
a=3
a^2=9
c=2(distance from center to foci on the major axis)
c^2=4
c^2=a^2-b^2
b^2=a^2-c^2=9-4=5
equation of given ellipse:
