Answer:
The cube of twice a number.
Twice a quantity usually indicates to take two of the things in question; usually this indicates to multiply by 2. Thus "twice a number x" can be written symbolically as 2x. If this is part of a problem, say twice a number x is 6, then we can rewrite algebraically as 2x=6; dividing both sides by 2 yields x=3.

If you put it into the slope intercept from (x1,y1) and (x2,y2)
then subtract 3-8 and 2-5 you should get 5\3 as your answer.
