## Homework Statement

Characterize and Sketch several level sets for the function::

z=x

^{2}+y

^{2}/2(x+y)

## Homework Equations

N/A

## The Attempt at a Solution

i tried to set a z, for example say for z=0.5, then i get in the form of::

x+y = x

^{2}+y

^{2}

now its the difficult part, graphing it, i know doing on the computer is easy, but i want to know how to do it by hand, any tricks or tips that will make it easier to do so, rather than point by point.

same problem with z=k

2k(x+y)=x

^{2}+y

^{2}
