where is the center?

idk.. it doesn't say... it just says what i typed in :/

i know, you have to find it

the co-vertices lie along the minor axis

ok, how do we do that?

the midpoint of this minor axis is where the center is

minor is vertical or horizontal?

(0,-3) and (0,3) lie on what line?

so would the center be (0,0) ??

yep

the x-axis?

no, you have it flipped

okay so how do i write this equation??
oh the y axis?

so the minor axis is vertical

the major must be horizontal

ohh okay :) so its on the major axis?

what is

(0,-3) and (0,3) ?

no they are on the minor axis because they are co-vertices

not vertices

ohh okay i see... what do we do now??

how long is the minor axis?

idk :/ how do i find that?? i just know the major axis is 10...

what's the distance between the co-vertices?

6? so is 6 the length of the minor axis?

yes good

cut that in half to get 3
that's the length of the semi-minor axis

so b = 3

you know the center is (0,0) because you just found this, so (h,k) = (0,0)

okay :)
so far we have this?
(x-0)^2/(a^2) + (y-0)^2/(3^2)=1
??

good, the only thing you need is 'a'

how do we find that? do we square root 10? if so, can i just write sq.rt.10?

no, the length of the major axis is 10
the length of the semi-major axis is ____

5?

so a = 5

you can simplify it more if you want

|dw:1356131176856:dw|

but when it says write the equation, what format do they want it in?

there are many formats, but that's probably the best one

the simplified version?

yeah

kk so we are done now?? htats it?

yes

kk thank youu :)
