**Reiny**, Thursday, November 18, 2010 at 7:50pmfirst you need the midpoint of the line segment

which is (4,3)

now find the slope of the given line which is 2/3

so the slope of the perpendicular is -3/2

equation:

y = (-3/2)x + b

but you know (4,3) lies on it , so

3= (-3/2)(4) + b

3 = -6 + b

b = 9

y = (-3/2)x + 9
