Well, remember...
to find the slope you take the Y value from the second pair of numbers (2) and you subtract the Y value from the first pair (11). that gives you the numerator of the slope. for the denominator, you take X from pair 2 minus X from pair 1 (8-11).
so that gives you the slope of the line that goes through those 2 points.
to find a perpendicular line, you multiply the slope by -1.
you should be able to figure it out from there.

(2-11)/(8-11)= -9/-3=3
perpendicular slope: -1/3

Slope:
m=(y2-y1)/(x2-x1)
m=(2-11)/(8-11)
m=-9/-3=3
The perpendicular of that would be -1/3.
