@Loser66 can you help me again please? i dont mean to be bother.

The same. Tell me what you think

Answer 3

well the center is (0,-2)
a=3
b=1

Answer 4

yup

Answer 5

this is a ellispse right?

Answer 6

yup

Answer 7

the equation of an ellipse is x2/a2 + y2/b2 = 1

so is it x2/9 + y2/1 = 1?

Answer 8

This is a VERTICAL ellipse, hence the standard formula will have y in the front.
\(\dfrac{y^2}{a^2}+\dfrac{x^2}{b^2}=1\)

Answer 9

Got me?

Answer 10

y2/1 +x2/9=1

Answer 11

a is ALWAYS with the main axis (y in this case)

Answer 12

y2/9+x2/1

Answer 13

If it is a HORIZONTAL one, then x will go first and a will go with x.
