$y=4\cdot{x}+20$

Step-by-step explanation:

Let the regresssion line be linear because of a constant amount of money coming in. Let y be the total amount of money in the box and x the weeks of adding to the box:

$y=m\cdot{x}+c$

We know that he puts $20 in the box from his birthday and $4 every week for x weeks. Therefore the total amount of money will be:

$y=4\cdot{x}+20$
