Hi,
 

Passing through the point (2,8) and parallel to the line equation 3x+2y=13
parallel to the line equation 
3x+2y=13   OR y = (-3/2)x + 13/2   m = (-3/2)
Parallel  lines have identical slopes
New Line
 y = (-3/2)x + b  |Using ordered pair (2,8) to solve for b
 8 = (-3/2)*2 + b
 11 = b
  y =  (-3/2)x + 11  OR 3x+2y = 22
