Understanding distance-time graphs is pretty easy once you know what the lines mean! Here’s a simple breakdown:

1. Flat Line: When you see a flat line, it means the object isn’t moving at all. It’s just sitting still.

2. Positive Slope: If the line goes up, that shows the object is moving away from where it started. If the line is steeper, it means the object is going faster.

3. Negative Slope: A line that goes down tells us the object is coming back to where it started.

To figure out how fast something is moving, you can find the slope using this formula:

$$\text{slope} = \frac{\text{change in distance}}{\text{change in time}}$$

Using this formula helps make it easy to see how things move!
