Step-by-step explanation:

y is a function of x, because for each input x there is only one output y. (It doesn't work backwards. x is not a function of y. not sure if you needed that but there it is!)

The equation would be

y=9.60x

where y is the amount Lin's sister earns and x is the amount of hours she works
