How do you determine if a slope is positive, negative, or zero?

Back

A positive slope rises from left to right, a negative slope falls from left to right, and a zero slope is horizontal.

Back

Front

What is the slope of the line that passes through the points (3, 4) and (3, -9)?

Back

The slope is undefined because the x-coordinates are the same.

Front

What does it mean if a line has a negative slope?

Back

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