To represent \(5 \cdot (-7)\), you can visualize it as five groups of \(-7\), which is essentially moving 5 times to the left on a number line (since \(-7\) is negative).
Thus, the correct representation on the number line is:
**Number line showing 5 arrows back to back pointing left. The first arrow starts at 0. Each arrow has a value of negative 7.**
This reflects the operation of adding \(-7\) a total of 5 times, resulting in \(-35\).
Thus, the correct representation on the number line is:
**Number line showing 5 arrows back to back pointing left. The first arrow starts at 0. Each arrow has a value of negative 7.**
This reflects the operation of adding \(-7\) a total of 5 times, resulting in \(-35\).
