if two lines are perpendicular to each other their slopes are negative reciprocals of each other
the negative reciprocal of 2 is -(1/2)

Close, the slope of the line perpendicular to y = 2x + 1 is -1/2. This is because the slope of a line perpendicular to another line is the negative reciprocal of the slope of the original line. In general, this means that the slope of the line perpendicular to y = mx + b is -1/m.
