4x - 2y = 8     re-arrnge to

y = 2x -4        slope , m = 2    parallel slope is the same   m  = 2

 

point slope form of new line through 0, -8

   y - - 8 =  2 (x -0)

   y = 2x - 8                          ( could have just changed the y intercept to -8   to get this result with a little less calc)
