Enter the letters of the points that satisfy the inequality


\[y > -\frac{1}{2} x + 2.\]
 


For example, if you think points and lie on the line, then say "B, D, G".

y  >  -  (1/2)x  + 2

 

Easiest way is to list the coordinates of the points and test these in the inequality

        (x, y)

A = (3,3)    OK

B = (-5,- 4) No

C = (-4, 1)   No

D = (6, -1) No

E = (6,6)  OK

F = (-2, -2)  No

G = (-3, 5)  OK

H = (3, -6)  No

I  = ( 2, 4)  OK

J  = (2, -3) No
