Slope is just the rate of change of a line. There are 4 slopes for a line: positive, negative, zero, and no slope. Slope can be calculated on a graph by looking at the change in y (rise) over the change in x (run) and by the equation: m = (y2 – y1)/(x2 – x1), where m = slope and (x1, y1) is one coordinate point and (y1, y2) is another coordinate point.
