This is a simple case of solving the inequality:

4–11x ≥ (−2x+32)/2

Multiply both sides by 2

8 - 22x ≥ −2x+32

Add both sides by 22x

8 ≥ 20x+32

Subtract 32 from both sides

-24 ≥ 20x

Divide both sides by 20

-6/5 ≥ x

So x is less than or equal to some negative number. The only graph that fulfills this requirement is A.
