Hi!
So what you want to do is just plug in the coordinates!
A works because anything times 0 is 0 and 5 is equal to 5
B doesn't work beause y is less than the number which cannot happen
C works because 10 is greater than or equal to 3
D works because 2 is greater than or equal to 1
E doesn't work because 5 isn't greater than or equal to 7
F doesn't work because 4 isn't greater than or equal to 5
Final answers are A, C, D
Hope this helps!
