What does it mean for a relation to be a function?

Back

A relation is a function if each input (x-value) has exactly one output (y-value).

Is the relation represented by a vertical line a function?

Back

No, because a vertical line intersects the graph at more than one point, meaning one input has multiple outputs.

What does a flat line on a distance-time graph indicate?

Back

A flat line indicates that the object is not moving.

What does a sloped line on a distance-time graph represent?

Back

A sloped line indicates that the object is moving; the steeper the slope, the faster the object is moving.

How can you determine which runner was faster from a distance-time graph?

Back

The runner with the steeper slope on the graph is the faster runner.

What does it mean if a graph shows a constant speed?

Back

It means the object is covering equal distances in equal intervals of time.
