Intervals of increasing/decreasing

Front

What is an interval of increasing on a graph?

Back

An interval of increasing on a graph is a section where the y-values rise as the x-values increase.

What is an interval of decreasing on a graph?

Back

An interval of decreasing on a graph is a section where the y-values fall as the x-values increase.

How can you identify high tides from a graph of water depth?

Back

High tides are identified as the peaks or highest points on the graph.

Front

How can you identify low tides from a graph of water depth?

Back

Low tides are identified as the troughs or lowest points on the graph.

Front

What does a positive slope indicate in a distance-time graph?

Back

A positive slope indicates that the object is moving away from the starting point.

Front

What does a negative slope indicate in a distance-time graph?

Back

A negative slope indicates that the object is moving back towards the starting point.

Front

What does a slope of zero indicate in a distance-time graph?

Back

A slope of zero indicates that the object is stationary.

Front

What is the significance of the steepness of a slope?

Back

The steepness of a slope indicates the rate of change; a steeper slope means a faster rate of change.

Front

What does it mean if a graph is flat (horizontal)?

Back

A flat graph indicates that there is no change in the y-value as the x-value changes.

How can you determine the time intervals of increasing distance in a hike?

Back

Look for sections of the graph where the slope is positive.
