Answer 1

all y >= -3

Answer 2

what do you mean all?

Answer 3

how do I find out which one is not a solution

Answer 4

well....y > = -3....it is stating y is greater then or equal to -3.
So anything greater then or equal to a -3 can match the solution.
Numbers further right on the number line are greater then the numbers to the left. Example : -3 > -4 (-3 is greater then -4 because it is on the right side of -4)
In this problem, y can be -3,-2,-1,0,1,2,etc...
