The second number in the ordered pair (0,4) is the Y value.
The first equation in each answer is for just the Y value
For A it says y <4, this is not true since the Y value is 4.
B says Y is greater than or equal to 4, this is true because it equals 4.
C is also true because it equals 4.
D is false.
Now you are down to either B or C being the answer, replace x with 0 in the second equation of each answer:
B: 4 < 0+5 is true, because 4 is less than 5.
C. 4 ≥ 0+5 is false, because 4 is not greater than or equal to 5.
This means the correct answer would be B.
