D

To find which ordered pair is not a solution, substitute the coordinates into the left side of the inequality and check validity of result.

A (2, 8 )

- 4 + 24 = 20 > 8

(2, 8 ) is a solution

B (- 1, 4 )

2 + 12 = 14 > 8

(- 1, 4 ) is a solution

C (3, 11 )

- 6 + 33 = 27 > 8

(3, 11 ) is a solution

D  (- 2, 1 )

4 + 3 = 7 < 8

(- 2, 1 ) is not a solution

D (0, 6 )

0 + 18 = 18 > 8

(0, 6 ) is a solution
