Types of Slope

9th Grade50 minutes

Learning Objective

I can determine if a line has a positive, negative, zero, or undefined slope from a graph.

Key Concepts

A slope describes the steepness of a line.

Slope, represented by the letter m, is calculated as rise over run, which is the change in y over the change in x.

A line that goes up from left to right has a positive slope, a line that goes down from left to right has a negative slope, a horizontal line has a zero slope, and a vertical line has an undefined slope.
