Checkpoint: Ellipses Solution

Write the equation of the ellipse. Label the center, vertices, and co-vertices. Name the length of the major and minor axis.

$\frac{{(x + 2)}^{2}}{4} + \frac{{(y - 1)}^{2}}{9} = 1$

Major axis: 6
Minor axis: 4

Note

Q: What is the location of the center on the major and minor axis?

A: The midpoint

Q: Why is marking the vertices and co-vertices on a graph or an ellipse helpful?

A: They help to more accurately mark a graph of an ellipse when you are not using technology.
