Question 151138
The slope-intercept formula of a line is y = mx + b where m is the slope and b is                     
                                                          the y-intercept
4x-2y-1 = 0 

-2y = -4x + 1

  y = 2x - 1/2

  The slope of the line is 2 and a y-intercept of -1/2. Any line parallel to this line must also have a slope of 2.
