= 16*(-2)/4 + 10

= -32/4 + 10

= -8 + 10

= 2

The amount Lin's sister earns at her part-time job is proportional to the number

gulaghasi [49]

Answer:

$y = 9.6x$

Yes, y is a function of x.

$x = \frac{5}{48} y$

Step-by-step explanation:

For a proportional relation, the equation is given by:

$y = kx$

where k is the unit rate of change.

We were told that, Lin's sister earns $9.6 per hour.

This means k=9.6.

We substitute to get:

$y = 9.6x$

We could rewrite this as

$y(x) = 9.6x$

Yes, y is a function of x.

To obtain an equation describing x as a function of y, we solve for x to get:

$x = \frac{1}{9.6} y$
