Lesson 10 Qualitative Graphs Review

Front

What is a qualitative graph?

Back

A qualitative graph is a type of graph that represents the relationship between variables without using numerical values, focusing instead on the general trends and behaviors of the data.

Front

What does a zero slope indicate on a graph?

Back

A zero slope indicates that there is no change in the y-value as the x-value changes, meaning the object is at a constant height or position.

Front

What does a positive slope indicate on a graph?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, showing that the object is moving upward or away from the reference point.

Front

What does a negative slope indicate on a graph?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, showing that the object is moving downward or back toward the reference point.

Front

How can you identify non-linear intervals on a graph?

Back

Non-linear intervals can be identified by looking for sections of the graph where the slope changes or is not constant, indicating a change in the rate of movement.

Front

What does it mean when a graph section is described as 'increasing'?

Back

An 'increasing' section of a graph means that the y-value is rising as the x-value increases, indicating that the object is moving away from the starting point.

Front

What does it mean when a graph section is described as 'decreasing'?

Back

A 'decreasing' section of a graph means that the y-value is falling as the x-value increases, indicating that the object is moving back toward the starting point.

Front

What is the significance of the starting point on a graph?

Back

The starting point on a graph is the initial position of the object, often represented by the origin (0,0) or another defined point, from which all movements are measured.

Front

How can you determine the time taken to return to the starting point from a graph?

Back

The time taken to return to the starting point can be determined by identifying the point on the graph where the y-value returns to zero and reading the corresponding x-value.

Front

What does it mean if a graph shows a flat line?

Back

A flat line on a graph indicates that the object is stationary, meaning there is no change in position over time.
