Explanation & Answer

Thank you for the opportunity to help you with your question! Hope your day is going well!

We know that Henry is making 45 per day, but he already had 200 dollars.

let x=days

Then y=45x+200

To know this is correct, let's look at the first couple of days

Before he started work, x=0

y=45(0)+200

y=200 (which is the exact amount he had before working, so check!)

Day 1:

y=45(1)+200

y=245 (which makes sense, since he already had 200 and we added 45 to it)

Day 2

y=45(2)+200

y=290 (which once again makes sense).

Hence this is the correct linear equation.

Please let me know if you need any clarification. I'm always happy to answer your questions. Leave a positive review if you are happy!
