A line has a slope of -2/3 and passes through the point 
  (-3, 8), 
what is the equation of the line?
 We know, that the standard equation of a line is
  y = mx + b
  We are given y, m and x
Let's plug these into the equation and solve for b
   
   
  The 3's cancel,
 
      8 = -
    
      2
      /
    3
  (-3) + b
  Leaving us with 
  8 = - 2(-1) + b
  Solving for b
b = 8 - 2 = 6
  The equation of this line is 
   
      y = 
     
      2
      /
     3
  x + 6
