Understanding Distance on the Number Line
To find the distance between two points on a number line, follow these steps:
1. Identify the Points
We have two points: -7 and +3.
2. Use the Distance Formula
The distance between two points \( a \) and \( b \) on a number line is calculated using the formula:
Distance = |a - b|
3. Calculate the Distance
Here, we'll calculate the distance between -7 and +3:
Distance = |-7 - 3|
Distance = |-10|
Distance = 10 units
Visualizing the Calculation
- Starting from -7, if you move towards the right to reach 0, that is 7 units.
- Then, moving from 0 to +3 is an additional 3 units.
Thus, the total distance from -7 to +3 is:
7 units (to reach 0) + 3 units (to reach +3) = 10 units.
Conclusion
The correct answer is indeed option 'A', which states that the distance between -7 and +3 is 10 units. This method can be applied to find the distance between any two points on the number line.

Understanding Negative Integers
Negative integers are whole numbers that are less than zero. They are represented on the number line to the left of zero.
Identifying the Options
Let's analyze each option provided in the question:
  • -2: This is a negative integer because it is less than zero.
  • 3: This is a positive integer as it is greater than zero.
  • 0: This is neither negative nor positive; it is considered neutral.
  • +5: This is also a positive integer as it is greater than zero.

Conclusion
From the analysis, the only number that qualifies as a negative integer is -2. Thus, the correct answer is option A.
Understanding negative integers is essential as they play a significant role in various mathematical concepts, including temperature readings, financial transactions (like debts), and more. Recognizing the distinction between positive and negative integers helps in performing arithmetic operations accurately.

Understanding the Bank Transaction
To find your new balance after making a deposit and a withdrawal, we can break down the transactions step by step.
Initial Balance
- You start with ₹0 in your bank account.
Deposit Amount
- You deposit ₹50 into your account.
- New balance after the deposit:
- ₹0 + ₹50 = ₹50

Withdrawal Amount
- You then withdraw ₹70 from your account.
- New balance after the withdrawal:
- ₹50 - ₹70 = ₹-20

Final Balance
- After completing both transactions:
- Your balance is now ₹-20.
This means you are in a negative balance of ₹20, indicating that you owe the bank ₹20. Hence, the correct answer is option 'A', which states your balance is ₹-20.
Understanding how to manage deposits and withdrawals is essential for keeping track of your finances!
