if the variables x and y vary directly,then y+=+kx
use the given values
x+=+1%2F2%29+and+%7B%7B%7By+=+6
replace x and y in y+=+kx to find k
6+=+k%281%2F2%29
6%2F%281%2F2%29+=+k
12+=+k
so, equation is highlight%28y+=+12x%29

if the variables x and y vary inversely,then y+=+k%2Fx
then 6+=+k%2F%281%2F2%29
6%281%2F2%29+=+k
+k=3 and equation is highlight%28y+=+3%2Fx%29
