Question
Find an equation of variation in which y varies inversely as x and the following is true:
y=31, when x=4
Originally, I mixed up the equations of inverse and direct variation, and got 31=m(4)
-----
b
Obviously, I got it wrong, but I've gone ahead and redid the problem, and I'd just like somebody to check it for me:
y=k/x
31=4K
(divide both sides by 4)
y=7.75
y=31, when x=4
