Question 1: Assume that y varies inversely with x. If y=9 when x=7, find y when x=2. Enter in any fractions using a / (e. g. "1/2" is the same as 12 and 1 1/2 is the same as 112). Question 2:Assume that y varies directly with x. If y=9 when x=−3, find x when y=6. Enter in any fractions using a / (e. g. "1/2" is the same as 12).

Question 3:Assume that y varies directly with x. If y=−4 when x=2, find y when x=−6. Enter in any fractions using a / (e. g. "1/2" is the same as 12).
