Write an equation for the ellipse in standard form whose foci: (-3,4) and (7,4) passes through the point (2,1)
***
Given foci data shows ellipse has a horizontal major axis.
Its standard form of equation: ,a>b, (h,k)=(x,y) coordinates of center.
...
center: (2,4)
plug in coordinates of center and given point(2,1)
0+9/b^2=1
b^2=9
b=√9=3
c=5(distance from center to foci
c^2=25
c^2=a^2-b^2
a^2=c^2+b^2=25+9=34
Equation of given ellipse:
