So if x people were surveyed, 
people owned a bike and 
did not.
The difference between them is 72:
x-\frac{1}{8} [/tex] =72
so this means that
x=72
let's simplify:
x=72
and divide by 3:
x=24
and mupliply by 4:
x=96
so 96 people were surveyed

Using hit and trial, you van find it pretty easily-
- Putting x=0, we get y=-3
- Putting x=1, we get y=-1
- Putting x=2, we get y=5
You can try it for yourself as well, for me, I couldn't find any other option appropriate.
