Hi
x is {1,  2, __,  -12}
y is {12,__,  3,   __}
Let k represent the constant that x and y vary inversely by:
that is:  y = x/k  
 12 = 1/k      |Using ordered pair(1,12) to solve for k
  k = 1/12
  {{{y = x/12}}}      when x = 2
 y= 2/12 = 1/6            
   {{{y = x/12}}}     when y = 3
   3 = x/12
     x = 36
   {{{y = x/12}}}      when x = -12
   y =  -12/12 = -1
