Line Graphs and Coordinate Planes

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 coordinate plane?

Back

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

Front

What does the y-axis represent in a coordinate plane?

Back

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

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written in the form (x, y).

Front

How do you read a line graph?

Back

To read a line graph, look at the x-axis for the independent variable and the y-axis for the dependent variable. Follow the line to see how the dependent variable changes with the independent variable.

Front

What is the purpose of a coordinate plane?

Back

A coordinate plane is used to graph points, lines, and curves, allowing for the visualization of relationships between variables.

Front

What is the x-coordinate in an ordered pair?

Back

The x-coordinate is the first number in an ordered pair that indicates the position along the x-axis.

Front

What is the y-coordinate in an ordered pair?

Back

The y-coordinate is the second number in an ordered pair that indicates the position along the y-axis.

Front

How can 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 y divided by the change in x between two points on the line.

Front

What does it mean for a population to remain constant on a graph?

Back

When a population remains constant on a graph, it means that there is no change in the population size over a specific period, represented by a horizontal line.
