Reading 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 used to show trends over time.

What does the x-axis represent in a graph?

Back

The x-axis is the horizontal line in a graph that typically represents the independent variable or the input values.

Front

What does the y-axis represent in a graph?

Back

The y-axis is the vertical line in a graph that typically represents the dependent variable or the output values.

Front

How do you determine the slope of a line on a graph?

Back

The slope of a line is determined by the rise over run, which is the change in the y-values divided by the change in the x-values between two points on the line.

Front

What is the purpose of a graph?

Back

The purpose of a graph is to visually represent data to make it easier to understand trends, relationships, and patterns.

Front

What does it mean when two lines on a graph intersect?

Back

When two lines on a graph intersect, it indicates that the two variables represented by the lines have the same value at that point.

Front

What is a data point in a graph?

Back

A data point is a single value that represents a specific measurement or observation in the context of the graph.

Front

How can you find the average from a graph?

Back

To find the average from a graph, you can sum the values represented by the data points and then divide by the number of data points.

Front

What does a flat line on a graph indicate?

Back

A flat line on a graph indicates that there is no change in the value of the dependent variable as the independent variable changes.

Front

What is the significance of the scale on a graph?

Back

The scale on a graph indicates the range of values represented on the axes and helps to accurately interpret the data.
