What does the slope (m) represent in a linear function?

Back

The slope (m) represents the rate of change of y with respect to x; it indicates how steep the line is.

What is the significance of the slope being positive, negative, zero, or undefined?

Back

A positive slope indicates the line rises, a negative slope indicates it falls, a zero slope indicates a horizontal line, and an undefined slope indicates a vertical line.
