phi · Answer

linear implies the equation is a line.  do you what the equation of a line looks like?  It will not have squares, absolute values, or x*y terms.

anonymous · Answer

so is it answer choice 2

phi · Answer

choice two has a x*y term.  so it is not linear.  linear means ax+by+c=0  where a,b,c are numbers.  Notice x and y are variables to the first power.  You can rearrange the terms, for example: c+ax= -by
