D. State all 4 vertices of the ellipse.
8. (x2)/25 + (y2)/9 = 1
9. (x2)/9 + (y2)/36 = 1

See below

Step-by-step explanation:

Recall that for an ellipse in the form of where , then its vertices are at and its co-vertices are at .

8) Its vertices are and . Its co-vertices are and .

Recall that for an ellipse in the form of where , its vertices are at and the co-vertices are at .

9) Its vertices are at and . Its co-vertices are at and .

Also remember that vertices are located on the major axis and co-vertices are located on the minor axis.
