Juan always saves the same amount from his weekly allowance. The table shows how much he has saved at different times.



Which equation represents the situation?



Juan’s Savings


Weeks
3, 6, 9, 12
Amount saved 19, 28, 37, 46





A.


y – 3 = −3(x – 19)


B.


y – 28 = 3(x – 6)


C.


y + 9 = −3(x + 37)


D.


y + 46 = 3(x – 12)
I'm pretty sure it's B.
