The two points in the first part of the question, are they two seperate points with an origin of 0,0 or are they one end to the other end of the rubber band. I think they are the 2nd of the options, as I tried to work it as the first, and the second part of the question didn't make any sense, but I wanted to ask to be sure. Thanks
The origin of the coordinate system is (0, 0) but the origin is not a point associated with the rubber band. The rubber band has two ends, one at each of the given points.
You would find the length of the rubber band by finding the 'rise' and the 'run' between the points, which form the legs of a right triangle, then use the pythagorean theorem to find the hypotenuse. The hypotenuse is the length of the rubber band.
