find a point on a square

a square has a vertex on each coordinate axis, a vertex at (19,99), and a vertex at (x,y). Find the value of the ordered pair (x,y)

The coordinates are 99,80. The process of getting there is interesting.

Hi nikkiheat If you draw a rough sketch of what the graph would look like then you'll hopefully see how the final vertex will relate to the others. There are a few different approaches you can take but I find visualising it is a great help and from the drawing you should hopefully come up with a solution. Hope this helps :-)
