Sketch x /5 + y /26 = 1.
Major vertices ; minor vertices ; foci —foci are always on the longer axis.
Example 8—
This is the same as Example 12 except the center is no longer at the point (0,0). It is moved to the point (6,-4).
Now the major vertices are . The minor vertices are . The foci are .
Weird numbers are intentionally chosen so that you know exactly where they come from.
