Remember: An inequality names a whole set of answers. A ray shows them all, and the wide side of the sign faces the bigger number.
Whole numbers on the line
1

x > −4. What is the smallest whole number that x can be?
12
Number the steps to decide if −2 is a solution of x > −5.
Yes, so −2 is a solution
On the number line, −2 is to the right of −5
Put −2 in for x: is −2 > −5?
Write the inequality x > −5
