I'm confused. @Bobo-i-bo Can you help?

Answer 6

@welshfella It sort of looks like the numbers I would have are 5 and 4, so it could be option B or D.

Take a look at this and play around with the sliders on the left side and observe what happens to the ellipse.

If it still doesn't help come back :)

Answer 8

@Bobo-i-bo It didn't help

Answer 9

Would it be option B?

No. Do you understand how an equation can represent a graph?

Answer 11

I think it might be option A now because when you do 4^2=16 and 5^2=25

Answer 12

That is the correct answer... but I'm not sure you understand why?
