This graph shows the total kilometers Jack has walked over time, represented by the line on a coordinate grid. The vertical axis (Y-axis) is labeled "Total distance walked (kilometers)" and measures the number of kilometers Jack has walked, while the horizontal axis (X-axis) likely represents time, although it is not explicitly labeled.

From the graph:

• At the start, Jack has walked about 2 kilometers (where the line intersects the Y-axis).
• The line moves upward linearly, indicating that Jack's walking distance increases steadily over time.
• By the end of the graph, Jack has walked 10 kilometers.

It seems like the relationship is linear, meaning Jack walks at a constant rate. You can calculate his walking rate (slope) by finding the change in the Y-axis (kilometers walked) over the change in the X-axis (time).

Would you like a more detailed breakdown of this, or do you have specific questions?

Follow-up questions:

1. How can we calculate Jack's walking rate based on this graph?
2. What does the initial 2 kilometers on the Y-axis represent?
3. How do you determine the slope of the line from a graph?
4. What kind of real-life scenarios would show a similar linear relationship?
5. What would it mean if the line became steeper or flatter?

Tip: In a distance vs. time graph, the slope (rise/run) represents the speed or rate at which distance is covered over time.
