Answer: Find the area of all figures and then add it together
Step-by-step explanation:
The last one is the only one that will work.
For the first one the y intercept is when x = 0. The point would be 0,4
The second one gives a point of (4,0)
The third one is nonsense. (4,4) is not on this line.
All of them
But if u had to pick one I would say addition or subtraction
