Slope is the ratio of vertical change to horizontal change. m = rise = y2 ( y1 = (y run x2 ( x1 (x. Rise is the amount of change on the y-axis and run is the amount of change on the x-axis. A line with positive slope “climbs up” when viewing from left to right and a line with negative slope “slides down” from left to right.

Interpret slope as a rate of change. The . slope. of a line describes the . rate of change. To find the rate of change between two data points, divide the difference of the y-coordinates by the. difference of the x-coordinates. The rate of change between (x1, y1) and (x2, y2) is m = . positive slope negative slope 0 slope undefined slope y = mx ...
