Transcribed Image Text:### Understanding Inequality Notation on Number Lines
The image contains four number lines (A, B, C, D) each demonstrating different ways to represent inequalities on a number line. Detailed explanations of each number line are provided below:
#### Number Line A
- An arrow extends indefinitely to both the left and right, indicating that the line continues towards negative and positive infinity, respectively.
- Whole numbers from -1 through 7 are marked on the line.
- Circles are drawn around the numbers 4 and 7.
- This representation shows that the inequality involves all numbers between 4 and 7, including 4 but not including 7 (notation: \( 4 \leq x < 7 \)).
#### Number Line B
- Similar to Number Line A, an arrow points in both the left and right directions.
- Whole numbers from -1 through 7 are indicated.
- Circles are marked around the numbers 4 and 7.
- The arrow pointing to the right starts from 7.
- This represents numbers greater than or equal to 7 in the inequality, while 4 is also included (notation: \( 4 \leq x \leq 7 \) or \( 4 \leq x \leq \infty \)).
#### Number Line C
- Arrows extend to both left and right, indicating continuity towards negative and positive infinity.
- Whole numbers from -1 through 7 are labeled.
- A circle surrounds the number 4, and another surrounds the number 7.
- The arrow pointing to the left starts from -1.
- This indicates all numbers less than 4 and all numbers equal to 7 (notation: \( x < 4 \) or \( x = 7 \)).
#### Number Line D
- An arrow points infinitely to the right only, suggesting the line extends towards positive infinity.
- All whole numbers from -1 through 7 are labeled.
- A circle surrounds the number 7.
- This represents all numbers less than or equal to 7 (notation: \( x \leq 7 \)).
By understanding these graphical representations on number lines, students can effectively visualize and interpret inequalities in mathematics.
