To find the slope of a line passing through two points, use the slope formula: (y2 - y1)/(x2 - x1). It's the change in y divided by the change in x, or the "rise over the run." In this case, the (x2, y2) point is (4, 9) and the (x1, y1) point is (-2, 7). The slope of the line is:
(9 - 7)/(4 - -2) = 2/6 = 1/3
Actually, it doesn't matter which point you use as (x2, y2) and (x1, y1). If you did it the other way around you would get the same answer:
(7 - 9)/(-2 - 4) = -2/-6 = 1/3
