The value of y varies directly with x. What is k the constant of variation for this function, and what is y for the given value of x?
y= 1/2 when x=6. Find y when x=3
Can someone explain this as they solve? Because I have a lot more of them, and I'd like to do the rest on my own :)
Thanks!

Best ResponseYou've already chosen the best response.1so y varies directly with x y ∝ x now removing the proportionality sign '∝' and putting constant k we get y=kx we know when y=1/2 , x =6 so 1/2 =k(6) so k=1/12
