Answer:
1/2
Step-by-step explanation:
To find out this problem, you do rise over run to find the slope. First choose two points that are directly sitting on a line. I used (-2,1) and (0,2). Then count the rise, up 1, then the run, over two and that's how you get your answer. :)
Answer:
x = 1

Answer:
(I don't know if this is correct)
To find the length of the rectangle, you need to first do 20 x 2 = 40 because when you finding the perimeter you have to do W + L + W + L = P (or Wx2 + Lx2 = P). You then subtract 40 from 68 (68 - 40) where you get 28 left. you then just divide 28/2 and you get 14. I may be way off but that's how I learned it.
