The image provided shows a vertical number line with markings from -2 to 7. The task appears to involve interpreting or using this number line, but since no specific problem is stated in the question, I will provide a general explanation of how to use such a number line and what kinds of problems can be solved with it.
Explanation of the Number Line:
1.
Structure:
- The number line is vertical, meaning numbers increase as you move upward and decrease as you move downward.
- The numbers are marked at regular intervals, starting from -2 at the bottom and going up to 7 at the top.
2.
Key Features:
- Each tick mark represents a unit increment.
- The zero point (0) is clearly visible, dividing the line into positive and negative sections.
- Positive numbers are above 0, and negative numbers are below 0.
Types of Problems That Can Be Solved Using This Number Line:
#### 1.
Locating Numbers:
- You can locate any integer between -2 and 7 on this number line by identifying its position relative to the ticks.
- For example, the number 4 is located four units above 0.
#### 2.
Comparing Numbers:
- You can compare two numbers by seeing which one is higher on the number line.
- For example, 5 is greater than 3 because 5 is positioned higher than 3.
#### 3.
Finding Distances Between Numbers:
- The distance between two numbers on a number line is the absolute value of their difference.
- For example, the distance between -1 and 3 is \( |3 - (-1)| = |3 + 1| = 4 \).
#### 4.
Performing Addition and Subtraction:
-
Addition: To add two numbers, start at the first number and move up by the second number.
- Example: To find \( 2 + 3 \), start at 2 and move up 3 units to reach 5.
-
Subtraction: To subtract one number from another, start at the first number and move down by the second number.
- Example: To find \( 5 - 2 \), start at 5 and move down 2 units to reach 3.
#### 5.
Understanding Intervals:
- You can identify intervals on the number line, such as all numbers between -1 and 4.
- This would include all numbers from -1 to 4, inclusive or exclusive depending on the context.
Example Problem and Solution:
Suppose the task is to find the distance between -2 and 5 on this number line.
Solution:
1. Identify the positions of -2 and 5 on the number line.
2. Calculate the distance using the formula for the absolute value of the difference:
\[
\text{Distance} = |5 - (-2)| = |5 + 2| = |7| = 7
\]
3. The distance between -2 and 5 is 7 units.
Final Answer:
If the task were to find the distance between -2 and 5, the answer would be:
\[
\boxed{7}
\]
