Do you know what direct and inverse variation is?

anonymous · Answer

no

igreen · Answer

Direct variation means that when you multiply something to 'x', you get 'y'.

igreen · Answer

Inverse variation means that when you divide something by 'x', you get 'y'.

igreen · Answer

So is something being divided here or multiplied?

What's 12 / 6? @nemoo112233

anonymous · Answer

2

igreen · Answer

Yep, and what's 8 / 3?

anonymous · Answer

2.6?

igreen · Answer

Yes, since 2 and 2.6 aren't the same, we know that this isn't a direct variation, so it must be an inverse variation.

Check:

2 * 12 = 24 
3 * 8 = 24 
4 * 6 = 24 

So it's an inverse variation. $\Large\color{lime}\checkmark$
