Answer:
y = 6/5x + 8
Step-by-step explanation:
m = 6/5
y - y1 = m (x - x1)
y - (-2) = 6/5(x - 5)
y + 2 = 6/5 x - 6
y = 6/5x + 8
19 x 1.39
8 x 1.24

"closed under addition and subtraction" means that if you add (or subtract) two polynomials, you get a polynomial**. If they mean does your work PROVE it, well, it does NOT prove it. But it is a good example showing that:
when you add (or subtract) polynomials, the result is also a polynomial.
**polynomial is an expression like 8x^2-5x-2 or
7-x^2+3 or
4x^3-10x^2-7
