A


                   B


                   C


                   D



          Answer

        The correct answer is D. The slope of the line is negative, so that rules out choices A and C. The rise of
        the line is (-5) and the run is 2. Slope is generally left as an improper fraction, rather than as a mixed
        number.




        Slope can also be calculated if you know any two points on the line. You can find the points yourself from
        a graph or you may be given the points without any graphical representation of the line. The formula
        follows:






        Example


        What is the slope of the line that passes through the points (4, -7) and (-2, 5)?
