To find the sum \( p + q \) where \( p = -19 \) and \( q = 12.1 \) using a number line, follow these steps:
1. **Locate \( p \) on the Number Line**: Begin by finding \(-19\) on a number line. It is located 19 units to the left of zero.
2. **Find \( q = 12.1 \)**: To find the sum \( p + q \), you need to move to the right from \(-19\) by the value of \( q \).
3. **Convert \( q \) into Steps**: Since \( q = 12.1 \), you will move 12.1 units to the right from \(-19\).
4. **Count the Spaces**:
- First, move 12 spaces to the right from \(-19\):
- Moving from \(-19\) to \(-7\) (which is \(-19 + 12 = -7\)) covers the first 12 units.
- Now, you need to move an additional \( 0.1 \) units to the right. This will take you from \(-7\) to \(-6.9\).
5. **Identify the Result**: After making the movement of \( 12.1 \) units to the right from \(-19\), you end up at \(-6.9\).
Thus, the sum \( p + q = -19 + 12.1 = -6.9 \).
