Well, I'm having trouble on some of my homework questions and looking to get help as soon as possible on one of them about inverse variation.

1. If y varies inversely as x and y = -3 when x = 9, find y when x = 81.

I will use the equation y = k/x but I have no idea how to plug the numbers in and then solve ;/

-3/9 = y/81

Solve for y.
You sure its not -3/81 = y/9?
My answer came out as -1/3 and I solved in 2 different ways.
UR right
