Answer
5/20 so 25%
Explanation
-96-(-86) -10 -2
------------= ------= -----= -2
82-87 -5 1
The 9 is in the tenths place so it should be 9x1/10. Meaning it would be 100+3x1+9x1/10+3x1,000
Putting both equations into standard form, we have the system
x -2y = 4
x -2y = -12
The lines these equations describe are
parallel.
