The phrase at least means that the expression is greater than or equal to some value.
y+9≥-1
Practice makes perfect
Every inequality has an inequality symbol and values or expressions on either side of this symbol. In this exercise, we have the phrase at least, which is the same thing as greater than or equal to. Therefore, the inequality symbol should be ≥.
... ≥ ...
On the left-hand side, we have the phrase: the sum of y and 9, which can be expressed algebraically with an addition.
y + 9
On the right-hand side, we have a constant. Putting these sides together, we have a complete inequality.
The sum of y and 9 is at least -1
y + 9 ≥ -1
