Hi,

Using the standard slope-intercept form for an equation of a line y = mx + b

  where m is the slope and b the y-intercept.

m+=%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+x%5B1%5D%29

L1:  (-6, -3), 

     (-10, 0)   m = -3/4,   y = (-3/4)x - 30/4

L2:  (3, 9), 

      (0, 5)    m = 4/3,     y = (3/4)x  + 5

Lines Perpendicular
