Hi,

Finding r

(6,-2),

(r,-6),   m=4  m+=%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+x%5B1%5D%29      

 %28-2-%28-6%29%29+%2F%286-r%29+=+4

    (-2-(-6)) = 4(6-r)

         4 = 4(6-r)

         4 = 24 - 4r

         -20 = -4r

           5 =r

Line thru Points (6,-2) and (5,-6) has slope of 4

  y -(-2) = 4(x-6)  0r  y = 4x - 26
