Final answer:
The correct interpretation of the inequality -5 < -6 on a number line is that -5 is located to the right of -6 on a number line.
Step-by-step explanation:
The correct interpretation of the inequality -5 < -6 on a number line is that -5 is located to the right of -6 on a number line. This can be visualized by imagining a number line with -6 to the left of 0 and -5 to the right of -6. Since -5 is greater than -6, it is further to the right on the number line.
