What is the rate of change in a linear relationship?

Back

The rate of change in a linear relationship is the ratio of the change in the dependent variable to the change in the independent variable, often represented as the slope of the line.

Front

How do you determine if a relation is a function?

Back

A relation is a function if each input (x-value) is associated with exactly one output (y-value). This means no x-value can map to more than one y-value.

What is a direct variation?

Front

What does it mean for a relationship to be linear?

Back

A linear relationship means that the graph of the relationship forms a straight line, indicating a constant rate of change between the variables.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x is zero.

Front

What is the difference between a function and a non-function?

Back

A function has a unique output for every input, while a non-function has at least one input that corresponds to multiple outputs.

Front

What is the concept of rate of change in real-world applications?

Back

The rate of change describes how one quantity changes in relation to another, often used in contexts like speed, cost per item, or growth rates.
