Question 391885: I really need some help. I don't udnerstand what they are talking about. thank you so much for your time
find the variation constant and an equation of variation where y varies directly as x and y =42 and x = 7
the variation constant is k=
Answer by Alan3354(69443) (Show Source): You can put this solution on YOUR website!
y varies directly with x means that when x increases, y increases also.
If x doubles, y doubles, etc.
y = k*x
or, y = some constant (some number) times x
----------
42 = k*7
k = 6
y = 6x
