Let's try to solve on our own and then look at our options. We need to add, since it says sum, two polynomials. It would look like: (2x-5y)+(x+y) Let's start with x.
2x+x=3x Now y. -5y+y=-4y We need to put 3x and -4y together.
The expression would look like 3x-4y, which is A.

step-by-step explanation:
the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.
