Which number line shows the correct way to find the sum p+q if p is positive and q is negative?(1 point)

Responses

A number line is shown with arrows at both ends, and hashmarks at unit intervals. The second point from the left is labeled p. Zero is marked at 6 intervals to the right of point p. A rightward curved arrow, labeled absolute value of q, starts at p and ends 4 intervals to the right of p.

A number line ranging from 0 in unit increments shows an arrow, labeled absolute value of q, starting at point p and ending 4 units to the right.

To find the sum \( p + q \) where \( p \) is positive and \( q \) is negative, you start from the position of \( p \) on the number line and then move to the left by the absolute value of \( q \) (which represents how far you go in the negative direction).

Given this, the correct representation among the options would show:

  1. Point \( p \) being located positively on the number line.
  2. An arrow pointing left from \( p \) indicating that you're subtracting the value of \( q \) (moving into the negative).

From the descriptions provided, the third option mentions that point \( p \) is marked on the seventh interval from the left (indicating it's positive), and there is a leftward arrow labeled with the absolute value of \( q \) moving from \( p \) to the second interval from the left (which accounts for moving into the negative).

This aligns perfectly with the operation of adding a negative number.

Therefore, the correct number line showing how to find the sum \( p + q \) is the third option.
