Question

.

Answer 1

The equation of an ellipse is given by \[\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1\]
In this case, a is the "radius" in the x direction and b is the "radius" in the y direction.
For 1), you have a=5 and b=2.
Just do the same for 2.

Answer 2

whoops. Sorry, a=2, b=5.

Answer 3

x^2/2^2+y^2/5^2=1?

Answer 4

Yes, exactly.

Answer 5

awesome! thankss

Answer 6

how about 2?

Answer 7

It's the same, you just have to change your a and b. So a = 2 and b = 12

Answer 8

x^2/2^2+y^2/12^2=1?

Answer 9

You got it. :)

Answer 10

thankssss so much!
