Front

What is a linear function?

Back

A linear function is a function that has a constant rate of change and its graph is a straight line.

Front

What is the relationship between a function and a relation?

Back

A function is a special type of relation where each input has exactly one output.

Front

What characterizes a nonlinear function?

Back

A nonlinear function has a varying slope, meaning its rate of change is not constant.

Front

How can you determine if a relation is a function?

Back

A relation is a function if each input corresponds to exactly one output.

Front

What is the slope of a line?

Back

The slope of a line is the ratio of the vertical change to the horizontal change between two points on the line.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates a horizontal line, meaning there is no vertical change as you move along the line.

Front

What does an undefined slope indicate?

Back

An undefined slope indicates a vertical line, where there is no horizontal change.

Front

What is the y-intercept of a linear function?

Back

The y-intercept is the point where the graph of the function crosses the y-axis.

Front

What is the x-intercept of a linear function?

Back

The x-intercept is the point where the graph of the function crosses the x-axis.
