The total distance covered = 4 km,
Since, initially he would be in rest,
So, his starting point would be 0.

Also, we can write,
Drawing number line:
Step 1: Draw a line.
Step 2: Make 12 marks in same distance.
Step 3: Starts from 0, then 1/3, 2/3, 3/3 and so on.
Thus, we can show Wayne's bike on a number line as below.
8x-3x+2=
-(3+2)
-(3-2)
-1
8x-1 is the correct answer
