For the line given by 3x 2y 4 0 find the slope of a line
     For the line given by, 3x + 2y + 4 = 0, find the slope of a line that is:  Parallel to the given line: m_parallel to the given lilne: m_parallel =  Perpendicular to the given line: m_perpendicular =  
  
  Solution
3x + 2y +4 =0
2y = -3x -4
y = (-3/2)x - 2
slope of above line = -3/2
slope of line parallel = -3/2
slope of line perppendicular = 2/3
