In the diagram below DE is a parallel to XY what is the value of y?

P(chicago, illinois)

You need to do x2-x1,y2-y1 and divide it by 2 and you should get (1,-3) 

2.8 with a bar over 8 means that it is 2.8 repeated. since we want to find which rational number is equal to 2.8 repeat, let’s calculate them.a) 22/9=2.4 repeatb) 24/9=2.6 repeatc) 26/9=2.8 repeatd) 28/9=3.1 repeatsince 2.8 repeat is the answer we’re looking for, the answer is c.
