The numbers that have a negative sign in front of them come first because they are less than 0. The other numbers can be ordered by what comes first. For example, 3 is bigger than 1 so 3 would come after 1.
Because as you see in those numbers, -8 is the smaller than -5, -1 because when you comparing number when it is negative, the higher the negative number is, the smaller that number would be. But with positive number, the higher the positive number is, the higher that number would become.
As the graph approach negative infinity the graph move to positive infinity as the graph approach positive infinity the graph move to negative infinity
