For the equation of the ellipse, figure out the following: Horizontal/Vertical, Center, Vertices, Co-Vertices, Foci.

When needed, convert radicals to decimals and round to 2 decimal points.

\frac{(x-1)^{2}}{25}+\frac{(y+3)^{2}}{144}=1

Orientation: (enter horizontal or vertical)

Center: ( , )

Vertices: ( , ) and ( , ) order does not matter

Co-Vertices: ( , ) and ( , ) order does not matter

Foci: ( , ) and ( , ) order does not matter

Identify the:

  • Vertex

  • Focus

  • Axis of Symmetry

  • Directrix

Then Sketch the graph. Make sure you label all the important points that you solved for above.

-20(x+2)=(y-8)^2
