To find the sum \( p + q \) where \( p \) is a positive number and \( q \) is a negative number, you can think of the situation on a number line. Since \( q \) is negative, it will be represented by moving leftward from \( p \).
Here's how to analyze the choices:
-
First option: \( p \) is at 5, and \( q \) (as absolute value) is 4, leading to \( p + q \) being at 1, which is correct as a representation of moving leftward.
-
Second option: This suggests moving right from \( p \), which is incorrect since \( q \) is negative.
-
Third option: With \( p \) at the seventh interval from the left and moving left to the second interval, that means \( q \) is -5, leading to \( p + q = 2 \), which doesn't accurately represent the sum.
-
Fourth option: This suggests moving right from \( p \) when \( q \) is negative, which is incorrect.
Thus, the first option correctly shows how to find \( p + q \) by moving to the left from \( p \) based on the negative value of \( q \).
