Writing an Inequality from a Graph
Write and translate Writing an Inequality from a Graph accurately in Grade 9 math. Learn to convert real-world situations into algebraic notation and equations.
Key Concepts
Property To write an inequality from a graph, identify the endpoint. An open circle means or <; a closed circle means $\ge$ or $\le$. The arrow shows the direction.
Examples An open circle at 1 with an arrow pointing right is $k 1$. A closed circle at 150 with an arrow pointing left is $z \le 150$.
Explanation Read the clues! The number with the circle is your starting point. Is it filled in? Use $\ge$ or $\le$. Is it open? Use or <. The arrow points to all the correct answers!
