Front

What does it mean if a table represents a linear function?

Back

The ratio of the change in the y value and the change in the x value is constant.

Front

How can you determine if a function is linear or nonlinear?

Back

If the ratio of the change in the y value and the change in the x value is not constant, it is a nonlinear function.

Front

What does a line that increases from left to right indicate about its slope?

Back

Positive slope.

Front

What is a linear function?

Back

A function that graphs to a straight line, showing a constant rate of change.

Front

What is a nonlinear function?

Back

A function that does not graph to a straight line, showing a variable rate of change.

Front

What is the slope of a line that decreases from left to right?

Back

Negative slope.

Front

What does a slope of zero indicate about a line?

Back

The line is horizontal.

What is the formula for calculating the slope (m) between two points (x1, y1) and (x2, y2)?

Back

m = (y2 - y1) / (x2 - x1).
