Front

What is a dependent quantity in a relationship?

Back

A dependent quantity is a variable whose value depends on the value of another variable. For example, in the relationship between gallons of gas and miles driven, miles driven is the dependent quantity.

Front

What is an independent quantity in a relationship?

Back

An independent quantity is a variable that stands alone and is not affected by other variables. For example, in the relationship between time and distance, time is often the independent quantity.

Front

What does the equation r = q + 10.1 represent?

Back

This equation shows that the value of r is always 10.1 more than the value of q.

Front

How do you identify the dependent and independent quantities from a table?

Back

The dependent quantity is usually the one that is affected by changes in the independent quantity. Look for the variable that changes in response to the other.

Front

What is the purpose of a graph in representing relationships?

Back

A graph visually displays the relationship between two variables, making it easier to see trends and patterns.

Front

What does the equation L = M / 2 mean in terms of laps and minutes?

Back

This equation indicates that for every 2 minutes Nick runs, he completes 1 lap.

Front

How can you determine which equation best represents a relationship?

Back

You can determine this by analyzing the data points and seeing which equation fits the data best, often through substitution or graphing.

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the rate of change between the dependent and independent variables. A steeper slope means a greater rate of change.

Front

What does it mean if a quantity is increasing in a graph?

Back

If a quantity is increasing in a graph, it means that as the independent variable increases, the dependent variable also increases.

Front

What is a linear relationship?

Back

A linear relationship is a relationship that can be represented by a straight line on a graph, indicating a constant rate of change.
