Selena babysits on the weekends. the equation y = 12x represents the amount of money she earns. what is the constant rate of proportionality?

I believe below are the choices, it can be found elsewhere.

A. 1 B. 6 C. 12 D. 24

The constant rat of the proportionality of Selena is letter C which is 12.

To get the answer, the equation should be y = 12x

we can fill in the table for x and y. (we know that to obtain the y, we have to multiply the x, times 2. So if x was for example 1, then y is 12.) The y in this case represents the earnings, per each week x.
