I don't know. I am only good at finding the slope from two given points. Someone else will probably help soon though. Sorry that I don't know.

staceyg · Answer

It's alright. Thanks anyway.

what does CONSTANT OF VARIATION mean? 
you need to know what is being asked fore you can tackle it.

staceyg · Answer

the ratio of two variables that are in direct variation?

nincompoop · Answer

AN EXAMPLE 

so let us say you have 
$$y = \frac{ 3 }{ 4 }x$$

the constant of variation is 3/4

nincompoop · Answer

so in summary, 
in the form
y= kx 
k is the constant of variation

staceyg · Answer

Thanks. So its -2 right?

staceyg · Answer

you just dived y by x basically?

nincompoop · Answer

:) it seems that you can solve after all

nincompoop · Answer

no. you find y by itself just like you did

staceyg · Answer

Oh then I got the answer the wrong way lol.

staceyg · Answer

So exactly how are you suppose to find k (constant of variation) with x and y?
