Vocabulary Review: Identify each statement based on whether or not it is an inequality.

15 < 32
-27 ≠ 3x
17x = 34
46 > 45

Inequality
NOT an inequality

10

Vocabulary Review: Complete each inequality with an inequality symbol from the left.

<
>

-2 __?__ 1
0.05 __?__ 0.5
8/6 __?__ 16/6
|-3.5| __?__ -4

Use Your Vocabulary: Categorize each inequality based on the boundary line of its graph.

y < 3x
2y - 3x ≤ 9
4y ≥ x - 1
y > -5x + 4

Solid boundary line
