B & C
If you negate and invert the slope of B, you get the slope of C
B slope: 5
C slope: -1/5
Determine which two equations represent perpendicular lines.
a)y=5/3
b)y=5x-5/3
c)y=-1/5x+5/3
d)y=1/5x-5/3

"I have worked on this equation for two days."
Well, you could have spend the two days better by learning some more maths :)
The answer is b) and c). Two lines:
y1 = m1 x + c1 and
y2 = m2 x + c2
are perpendicular if m1*m2 = -1
The reason why you have difficulties is because the problems you are given are too easy and can be solved by applying simple equations. If you only focus on these kind of problems you won't learn a lot and you'll continue to have difficulties.
