1. The problem is to place the speeds of 9 cars on a number line. 2. The speeds given are: $\{62, 77, 80, 54, 65, 67, 58, 63, 70\}$. 3. To place these on a number line, we identify the minimum and maximum values to set the scale. 4. Minimum speed is $54$ and maximum speed is $80$. 5. We can mark the number line from $50$ to $85$ for clarity. 6. Each speed is then represented as a point on this number line at its corresponding value. 7. For example, $54$ is near the start, $62$ and $63$ are close together, and $80$ is near the end. 8. This visual helps understand the distribution of car speeds on the highway. Final answer: The speeds $54, 58, 62, 63, 65, 67, 70, 77, 80$ are points on the number line from $50$ to $85$ at their respective values.
