    (-3,-13) and (-14,-15)


    Slope Formula:


               y2 - y1                              -15 - (-13)                       


    m = -----------------   >   m =      -------------------   =  


                x2 - x1                                  -14 - (-3)                       


     


               -2                              2


    m =  -----------   >    m =  ----------   (two negatives divided = positive)


                -11                            11


    __________________________________________________________________


    Or, 


    (-3,-13) and (-14,-15)




                  y1 - y2                        -13 - (-15)                     2


    m =  -----------------     >   m =  -------------    >   m =  ------


                  x1 - x2                         -3 - (-14)                       11
