Question 1096754
y=kx
then -2=k*-6
k=1/3; y=1/3 x
-------
3=k*9
k=1/3; y=1/3 x
-------
7=k*21
k=7/21=1/3, y=1/3 x
Y varies with x and the rule is y=1/3 x
====================
rewrite as y=x-2. y varies with x and the constant k = 1
====================
y=kx
-14=k(-7)
k=2
22=2*x
x=11
===================
