Y varies directly with x. Y =54 when x=9. Determine the direct variation equation and then determine y when x = 3.5
-----------------
Y varies directly with x
--> y = k*x --- k is a constant
=======================
y =54 when x=9 ---> 54 = k*9
k = 6
=================
determine y when x = 3.5
Think about it.
