Learn about positive and negative slopes in linear equations with this Khan Academy video tutorial.

A line that's flat has a slope of 0. If a line goes up as you move to the right, it has a positive slope. The steeper it is, the bigger the slope. If a line goes down as you move to the right, it has a negative slope. The steeper it is, the more negative the slope.

Help us do more. We'll get right to the point: we're asking you to help support Khan Academy. We're a nonprofit that relies on support from people like you.
