Graphing Inequalities
Master graphing inequalities in Grade 9 math — A closed circle includes the endpoint ($\ge, \le$), while an open circle excludes it (>, <). Part of Inequalities and Linear Systems for Grade 9.
Key Concepts
Property Use a number line to graph solutions. A closed circle includes the endpoint ($\ge, \le$), while an open circle excludes it ( , <).
Examples To graph $g 5.8$: Place an open circle at 5.8 and draw an arrow pointing right. To graph $r \le 2$: Place a closed circle at 2 and draw an arrow pointing left.
Explanation A closed circle means "you're invited" ($\ge$). An open circle means the party starts after that number ($ $). The arrow shows where all the fun is happening!
Common Questions
What is 'Graphing Inequalities' in Grade 9 math?
A closed circle includes the endpoint ($\ge, \le$), while an open circle excludes it (>, <). A closed circle includes the endpoint ($\ge, \le$), while an open circle excludes it (>, <).
How do you solve problems involving 'Graphing Inequalities'?
A closed circle includes the endpoint ($\ge, \le$), while an open circle excludes it (>, <). Explanation A closed circle means "you're invited" ($\ge$).
Why is 'Graphing Inequalities' an important Grade 9 math skill?
Write the inequality: $m \ge -4$ Takeaway: Look for the endpoint and direction!. Closed circles mean “or equal to,” and the arrow tells you whether the values go up or down the number line.
