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
