Can someone check all the correct points

Well, the inequality of x > 1, pretty much rules out any pairs that contain an x-coordinate with 1 or less, so we won't check those.

( 4 , 11), x = 4, y = 11

11 ⩾ 4(4) + 3

11 ⩾ 19   <---  is that true? nope

(2, 11), x = 2 , y = 11

11 ⩾ 4(2) + 3

11 ⩾ 11  <--- is that true?  well, yes, 11 = 11.

(4, 19), x = 4, y = 19

19 ⩾ 4(4) + 3

19 ⩾ 19 <--- is that true?, yeap
