List center: (2,-1)

the foci: -(sqrt 74) AND +(SQRT 74,0)

Major axis: x=2

Minor axis: y= -1

Vertices: (7,0) (-7,0) (0,5) (0,-5)

Is this correct?

**Damon**, Tuesday, November 1, 2011 at 6:45pmmajor semi axis 7

minor semi axis 5

these are half lengths from the center to the vertices

vertices

The center is at (2, -1)

therefore we have right and left vertices at 2+7 and at 2-7 in x when y is -1

thus

(9, -1) and (-5,-1)

Then the top and bottom vertices at

x = 2 an y = -1+5 and at -1-5

thus at

(2,4) and at (2,-6)
