Answer A. Use rise over run to do this next ti,e. Hope this helps. Also there is another way to figure this out. That is take your starting value (which in this case is 2), that's where the line starts and then subtract it from the end point of the line. Then go all the way over to the end point (in this case ten) and use that. Take those too numbers, divide them, and put it in fraction form. Boom! You did it
