Answer:
(2 x 5 x 5) / (2 x 3 x 4 x 5)
=40/120 
= 4/12
= 1/3

Y = 2x - 17, comparing to y = mx + c, slope m = 2.
If perpendicular, the new slope would be -1/2, that is the negative reciprocal of 2.
And passing through (-8 , 1).
using y = mx + c,  and x = -8,  y = 1,  m = -1/2
1 = -1/2*-8 + c
1 = 4 + c
1 - 4 = c
c =  -3
y = mx + c,  substituting m = -1/2, and c = -3,    y = -(1/2)x - 3.
Option C.
