  • 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.
