Write an equation or formula that represents the general relationship indicated. Then use the given information to find the unknown value.

If y is proportional to the square root of x, and y=6 when x= 1/4, what is y when x=9?

Im having a lot of difficulty with this problem, thank you for helping me!​

Do you know that:

If y is proportional to the square root of x,

then you can write,

y = k * (√x),

where k is a constant (constant of proportionality)

?
