The line:  y = (3/8)x + 6  has a slope of 3/8.

Any line perpendicular to this line will have a slope that is the negative reciprocal of 3/8. Ignore whatever is the y-intercept; that number has no effect upon whether or not two lines are perpendicular.

The negative reciprocal of  3/8  is  -8/3.

So, the correct choice is:  y  =(-8/3)x + 3. 

I have no idea why there is a '(-1,2)' within this equation.
