Interpret Line Graphs

Front

What is a line graph?

Back

A line graph is a type of chart that displays information as a series of data points called 'markers' connected by straight line segments. It is commonly used to visualize trends over time.

How do you interpret the slope of a line in a line graph?

Back

The slope of a line in a line graph indicates the rate of change between the two variables represented on the axes. A positive slope means an increase, while a negative slope indicates a decrease.

What does the y-axis represent in a line graph?

Back

The y-axis represents the dependent variable, which is the variable being measured or observed in the experiment or study.

Front

What does the x-axis represent in a line graph?

Back

The x-axis represents the independent variable, which is the variable that is manipulated or changed in the experiment.

How can you determine the difference between two points on a line graph?

Back

To determine the difference between two points on a line graph, find the values of the points on the y-axis and subtract one from the other.

What does a flat line indicate in a line graph?

Back

A flat line indicates that there is no change in the value of the dependent variable over the range of the independent variable.

How can you identify trends in a line graph?

Back

Trends in a line graph can be identified by observing the overall direction of the line (increasing, decreasing, or constant) and the steepness of the slope.

Front

What is the significance of data points in a line graph?

Back

Data points represent specific values of the variables being measured and are crucial for understanding the relationship between the independent and dependent variables.

Front

How do you read values from a line graph?

Back

To read values from a line graph, locate the data point on the line and project it vertically to the y-axis for the dependent variable and horizontally to the x-axis for the independent variable.

What is the importance of labeling axes in a line graph?

Back

Labeling axes is important because it provides context for the data being presented, allowing viewers to understand what each axis represents.
