Question 118826: i know this might not be the right collum but i cant find where to put direct variations im really sorry:(
but if you can could you help me again
suppose the ordered pair in each excercise are for the same direct variation.find each missing value
(3,2) and (6,y)
i really need help or its summer school again :(

You can put this solution on YOUR website!
Find the missing value in (3, 2) and (6, y) if the ordered pairs are for the same direct variation.
Start with:
y+=+kx for the direct variation equation, then substitute x=3 and y=2 to find the value of k, the constant of proportionality:
2+=+k%283%29 Divide both sides by 3.
k+=+2%2F3
Now the equation is:
y+=+%282%2F3%29x Substitute x = 6:
y+=+%282%2F3%296
y+=+4
This is the missing value.
