Question

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

Answer 1

Y + 46 = 3(x – 12)
I'm pretty sure it's B.  this is so long question

Answer 2

You're correct, it is B. If you plug in 3 (weeks) in for "x" and 19 (amount saved) for "y" you will get 0=0, which is a solution.
