what is the "following"

OpenStudy (anonymous):

okay so the equation of this ellipse is (x-h)^2/b^2 + (y-k)^2/a^2 = 1

OpenStudy (anonymous):

the vertex or center is at -2,4 a = 6 and b = 3

OpenStudy (anonymous):

no b because 36+9 = 45 square root of 45 = 3 sqrt5 but b is closest

OpenStudy (anonymous):

yea

OpenStudy (anonymous):

a is the right one
