3(n+2) ← algebraic expression
Answer:

Step-by-step explanation:

I am going to use (0, 1) and (2, 2)
We then go to our first point, (0, 1), and count how many points up it is until we are on the same x-axis of our y. This is 1. We then do the same thing for the y-axis. This is 2. It is rise over run, so the answer is 
(I hope this helps, have a nice day!)
You will need 82 1/4 1/2 tiles and 165 1/4 tiles
