What is the slope of a line?

Back

The slope of a line measures its steepness and direction. It is calculated as the change in y divided by the change in x (rise over run).

Front

What is the rate of change in a linear function?

Back

The rate of change is the same as the slope of the line, indicating how much y changes for a unit change in x.

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, meaning the line falls from left to right.
