Answer:
![y=4\cdot{x}+20](https://tex.z-dn.net/?f=y%3D4%5Ccdot%7Bx%7D%2B20)
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](https://tex.z-dn.net/?f=y%3Dm%5Ccdot%7Bx%7D%2Bc)
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](https://tex.z-dn.net/?f=y%3D4%5Ccdot%7Bx%7D%2B20)
