phi · Answer

Did you try to plot this, using simple numbers for b and c?  Try b=1 and c=2. After you have plotted the 3 points,  find the 4th point so you get a rectangle.

Okay well here are my options and I did what you said. The answer I got was (c,b)
(2c, 2b)
(b, c)
(c, b)

What's the problem?  Select (c,b), and move on to the next question.
