    If the points are (-1, 2) and (5, 7) then the slope of the line is 5/6 which is option B)

    Given two points, the slope = (y1-y2)/(x1-x2) = (7-2)/[5-(-1)] = Answer (B).

    Slope is rise/run. The rise is the change in Y. The run is the change in X.

    (7-2)/(5- -1)

    Simplifying that, the slope is 5/6
