Back

Slope is a measure of the steepness of a line, calculated as the rise over run.

Front

How do you calculate the slope of a line?

Back

Slope (m) = (change in y) / (change in x) or m = (y2 - y1) / (x2 - x1).

Front

What does a positive slope indicate?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as x increases, y decreases.
