is y=x/7 a direct variation????
i need a science fair project and fast i only gave 1 day to do it please please help me!!!!!!!!!!!!! o no what would i do
:(
BLAHHHHHHH !!!! I HAVE THE SAME PROBLEM
hello this carlos hernandez im in class and im bored nuthing to do omg bye have to go Bye

To determine if y = x/7 represents direct variation, we need to check if the equation can be written in the form y = kx, where k is a constant.
In this case, the equation is y = x/7. To put it in the form y = kx, we can multiply both sides of the equation by 7:
7y = x
Now we can see that the equation can be written as y = (1/7)x, which does match the form y = kx.
Therefore, the equation y = x/7 does represent direct variation, with the constant of variation being 1/7.
