Stretch: Writing and Graphing Inequalities
I can write an inequality from a real situation and identify which numbers are solutions.
🧠 The Challenge
inequalityat least (≥)at most (≤)solution setopen / closed circle
An inequality has many solutions. "At least 18" → x ≥ 18 uses a closed circle (18 included). "More than 18" → x > 18 uses an open circle.
👀 Worked Example
"You must be at least 48 inches to ride." Let h = height: h ≥ 48. So 48, 50, 60 all work; 47 does not.
✏️ Your Turn

1. "At least 10 points" (let p = points) is…
2. For x > 5, which number is NOT a solution?
3. "At most 3 hours" (let t = hours) is…
