You can put this solution on YOUR website! can you help me set up this problem and solve
find an equation of variation in which y varies directly as x,
and y=72 when x=6
----------
If y varies directly as x, y=kx
You need to find "k".
Substituting y=72 when x=6 you get:
72=k*6
k=12
EQUATION you want is y=12x
